#### Projects → Scenarios → Profitability Calculations
Calminer organises feasibility data in a nested hierarchy. A project defines the overarching mining context and exposes a one-to-many `scenarios` collection. Each scenario captures a self-contained assumption set and anchors derived artefacts such as financial inputs, simulation parameters, and profitability snapshots. Profitability calculations execute at the scenario scope; when triggered, the workflow in `services/calculations.py` persists a `ScenarioProfitability` record and can optionally roll results up to project level by creating a `ProjectProfitability` snapshot. Consumers typically surface the most recent metrics via the `latest_profitability` helpers on both ORM models.

# Data Import & Export Templates
This guide explains how to capture profitability, capex, and opex data for bulk upload or download using the standardized CSV and Excel templates. It builds on the field inventory documented in [data_import_export_field_inventory.md](data_import_export_field_inventory.md) and should be shared with anyone preparing data for the calculation engine.
## Template Package
The import/export toolkit contains two artifacts:
| File | Purpose |
| -------------------------- | ---------------------------------------------------------------------------------------------------- |
| `calminer_financials.csv` | Single-sheet CSV template for quick edits or integrations that generate structured rows dynamically. |
| `calminer_financials.xlsx` | Excel workbook with dedicated sheets, lookup lists, and validation rules for guided data capture. |
Always distribute the templates as a matched set so contributors can choose the format that best suits their workflow.
## CSV Workflow
### Structure Overview
The CSV template uses a `record_type` column to multiplex multiple logical tables inside one file. The exact column requirements, validation ranges, and record types are defined in the [Unified CSV Template Specification](data_import_export_field_inventory.md#unified-csv-template-specification). Key expectations:
- All rows include the scenario code (`scenario_code`), and optionally the project code, to keep capex and opex data aligned with profitability assumptions.
- Numeric cells must use `.` as the decimal separator and omit thousands separators, currency symbols, or formatting.
- Boolean values accept `true`/`false`, `yes`/`no`, or `1`/`0`; exporters should emit `true` or `false`.
### Authoring Steps
1. Populate at least one `profitability_input` row per scenario to establish the calculation context.
2. Add optional `profitability_impurity` rows where penalty modelling is required.
3. Capture capital costs via `capex_component` rows and configure options with a `capex_parameters` record.
4. Capture recurring costs via `processing_opex_component` rows. Add a `processing_opex_parameters` row to define escalation settings.
5. Validate the file against the rules listed in the specification prior to upload. Recommended tooling includes frictionless data checks or schema-enforced pipelines.
### Naming & Delivery
- Use the pattern `calminer_financials_<project-or-scenario-code>_<YYYYMMDD>.csv` when transferring files between teams.
- Provide a brief change log or summary per file so reviewers understand the scope of updates.
## Excel Workflow
### Workbook Layout
The Excel workbook contains structured sheets described in the [Excel Workbook Layout & Validation Rules](data_import_export_field_inventory.md#excel-workbook-layout--validation-rules) section. Highlights:
- The `Summary` sheet captures metadata (scenario, preparer, notes) that propagates into the downstream sheets via Excel Table references.
- Each data sheet (`Profitability_Input`, `Capex_Components`, `Processing_Opex`, etc.) is formatted as an Excel Table with frozen headers and data validation to enforce numeric ranges, lookup values, and boolean lists.
- The `Lookups` sheet holds named ranges for currencies, categories, and frequency values. Keep this sheet hidden to reduce accidental edits.
### Data Entry Checklist
- Confirm the `Summary` sheet lists every scenario included in the workbook before editing dependent sheets.
- Use the provided dropdowns for category, currency, frequency, and boolean fields to avoid invalid values.
- When copying data from other workbooks, paste values only to preserve validation rules.
- Turn on the totals row for component tables to quickly verify aggregate capex and opex amounts.
### Exporting From Excel
When exporting to CSV or ingesting into the API:
- Ensure the workbook is saved in `.xlsx` format; do not rename the sheets.
- If a CSV export is required, export each sheet separately and merge using the column headers defined in the CSV specification.
- Retain the original workbook as your source of truth; conversions to CSV should be treated as transient files for automation pipelines.
## Import Pipeline Expectations
The planned FastAPI import endpoints will perform the following checks:
- Validate record types, required columns, and numeric bounds according to the schemas described in the field inventory.
- Verify that referenced project/scenario codes exist and that foreign key relationships (components, parameters) target a single scenario within the file.
- Normalize casing for category slugs and currency codes to match the calculation services.
- Reject files that mix multiple projects unless intentionally enabled by configuration.
Until the endpoints are available, internal teams can use the specification as the contract for pre-validation scripts or interim ETL routines.
## Exporting Data
Export functionality will mirror the same structures:
- CSV exports will group rows by `record_type`, enabling direct round-tripping with minimal transformation.
- Excel exports will populate the same workbook sheets, preserving lookup lists and validation to support offline edits.
Document any local transformations or additional columns introduced during export so that downstream consumers can reconcile the data with the import templates.
## Change Management
- Increment the `import_version` value on the `Summary` sheet (and document the change here) whenever template-breaking updates occur.
- Update `data_import_export_field_inventory.md` first when adding or removing columns, then revise this guide to explain the user-facing workflow impact.
- Communicate updates to stakeholders and archive superseded templates to avoid drift.
## Stakeholder Review Checklist
Before finalising the templates for production use, circulate the following package to domain stakeholders (finance, engineering, data operations) and collect their feedback:
- `calminer_financials.csv` sample populated with representative profitability, capex, and opex data.
- `calminer_financials.xlsx` workbook showcasing all sheets, dropdowns, and validation rules.
- Links to documentation: this guide and the [field inventory](data_import_export_field_inventory.md).
- Summary of outstanding questions or assumptions (e.g., default currencies, additional categories).
Record the review session outcomes in the project tracker or meeting notes. Once sign-off is received, mark the stakeholder feedback step as complete in `.github/instructions/TODO.md` and proceed with implementation of import/export endpoints.

# Data Import/Export Field Inventory
This inventory captures the current data fields involved in profitability, capex, and opex workflows. It consolidates inputs accepted by the calculation services, derived outputs that should be available for export, and persisted snapshot columns.

## Unified CSV Template Specification
### Overview
The CSV template consolidates profitability, capex, and opex data into a single file. Each row declares its purpose via a `record_type` flag so that parsers can route data to the appropriate service. The format is UTF-8 with a header row and uses commas as delimiters. Empty string cells are interpreted as `null`. Monetary values must not include currency symbols; decimals use a period.
### Shared Columns
| Column | Required | Applies To | Validation & Notes |
| --------------- | -------- | ---------------------------- | --------------------------------------------------------------------------------- |
| `record_type` | Yes | All rows | Lowercase slug describing the row (see record types below). |

| `scenario_code` | No | All rows | Optional external scenario identifier; trimmed; max length 64. |
| `sequence` | No | Component and impurity rows | Optional positive integer governing ordering in UI exports. |
| `notes` | No | Component and parameter rows | Free-form text ≤ 500 chars; trimmed; mirrors request `notes` fields when present. |

### Validation Rules Summary
- Parsers must group rows by `project_code` + `scenario_code`; missing codes fall back to payload metadata supplied during import.
- `record_type` values outside the table must raise a validation error.
- Component identifiers (`component_id`) are optional for inserts but required to overwrite existing records.
- Decimal columns should accept up to two fractional places for currency-aligned fields (`amount`, `overall`, etc.) and up to six for percentage columns.
- Boolean columns accept `true`, `false`, `1`, `0`, `yes`, `no` (case-insensitive); exporters should emit `true`/`false`.
## Excel Workbook Layout & Validation Rules
### Workbook Structure
| Sheet Name | Purpose |
| -------------------------- | ------------------------------------------------------------------------------------- |
| `Summary` | Capture project/scenario metadata and import scope details. |
| `Profitability_Input` | Tabular input for `ProfitabilityCalculationRequest`. |
| `Profitability_Impurities` | Optional impurity rows linked to a scenario. |
| `Capex_Components` | Component-level spend records for the capex planner. |
| `Capex_Parameters` | Global capex parameters/options for a scenario. |
| `Opex` | Component-level recurring cost records for opex. |
| `Opex_Parameters` | Global opex parameters/options for a scenario. |
| `Lookups` | Controlled vocabulary lists consumed by data validation (categories, booleans, etc.). |
All sheets except `Lookups` start with a frozen header row and are formatted as Excel Tables (e.g., `tbl_profitability`). Tables enforce consistent column names and simplify import parsing.
### `Summary` Sheet
| Column | Required | Validation & Notes |
| ---------------- | -------- | --------------------------------------------------------------------------------- |
| `import_version` | Yes | Static text `v1`; used to detect template drift. |
| `project_code` | No | Matches shared `project_code`; max 64 chars; trimmed. |
| `scenario_code` | Yes | Identifier tying all sheets together; max 64 chars; duplicates allowed for batch. |
| `prepared_by` | No | Free-form text ≤ 128 chars. |
| `prepared_on` | No | Excel date; data validation restricts to dates ≥ `TODAY()-365`. |
| `notes` | No | Free-form text ≤ 500 chars; carry-over to import metadata. |
### `Profitability_Input`
Columns mirror the CSV specification; data validation rules apply per cell:
- Numeric fields (`ore_tonnage`, `reference_price`, etc.) use decimal validation with explicit min/max aligned to service constraints.
- Percentage fields (`head_grade_pct`, `discount_rate`) use decimals with bounds (e.g., 0–100). Apply `Data Validation → Decimal` settings.
- `currency_code` validation references `Lookups!$A:$A` (ISO codes list).
- Table default rows include scenario code reference via structured formula: `=[@Scenario_Code]` autocompletes when set.
### `Profitability_Impurities`
| Column | Required | Validation & Notes |
| --------------- | -------- | ----------------------------------------------------- |
| `scenario_code` | Yes | Drop-down referencing `Summary!C:C`; ensures linkage. |
| `name` | Yes | Text ≤ 64 chars; duplicates allowed. |

| `category` | Yes | Drop-down referencing `Lookups!category_values`. |
| `amount` | Yes | Decimal ≥ 0; formatted as currency (no symbol). |
| `currency` | No | Drop-down referencing `Lookups!currency_codes`. |
| `spend_year` | No | Whole number 0–120. |
| `notes` | No | Text ≤ 500 chars. |
### `Capex_Parameters`
Single-row table per scenario with structured references:
| Column | Required | Validation & Notes |
| -------------------------- | -------- | ------------------------------------------------------------ |
| `scenario_code` | Yes | Drop-down referencing `Summary!C:C`. |

| `persist_snapshot` | No | Drop-down referencing `Lookups!boolean_values` (True/False). |
| `notes` | No | Text ≤ 500 chars; maps to request options metadata. |
### `Opex`
| Column | Required | Validation & Notes |
| --------------- | -------- | -------------------------------------------------------------------------------------------------------------------------- |
| `scenario_code` | Yes | Drop-down referencing `Summary!C:C`. |
| `component_id` | No | Whole number ≥ 1; optional for inserts. |

| `frequency` | Yes | Drop-down referencing `Lookups!frequency_values` (annual, monthly, quarterly, once). |
| `currency` | No | Drop-down referencing `Lookups!currency_codes`. |
| `period_start` | No | Whole number ≥ 0; additional rule ensures `period_end` ≥ `period_start` via custom formula `=IF(ISBLANK(H2),TRUE,H2<=I2)`. |
| `period_end` | No | Whole number ≥ 0. |
| `notes` | No | Text ≤ 500 chars. |
### `Opex_Parameters`
| Column | Required | Validation & Notes |
| -------------------------- | -------- | ----------------------------------------------- |
| `scenario_code` | Yes | Drop-down referencing `Summary!C:C`. |
| `currency_code` | No | Drop-down referencing `Lookups!currency_codes`. |

| `persist_snapshot` | No | Drop-down referencing `Lookups!boolean_values`. |
| `snapshot_notes` | No | Text ≤ 500 chars. |
### `Lookups` Sheet
Contains named ranges used by validation rules:
| Named Range | Column Contents |
| ------------------ | ---------------------------------------------- |
| `currency_codes` | ISO 4217 codes supported by the platform. |
| `category_values` | Allowed capex categories (e.g., engineering). |
| `opex_categories` | Allowed opex categories (e.g., energy, labor). |
| `frequency_values` | `annual`, `monthly`, `quarterly`, `once`. |
| `boolean_values` | `TRUE`, `FALSE`. |
The sheet is hidden by default to avoid accidental edits. Import logic should bundle the lookup dictionary alongside the workbook to verify user-supplied values.
### Additional Validation Guidance
- Protect header rows to prevent renaming; enable `Allow Users to Edit Ranges` for data sections only.
- Apply conditional formatting to highlight missing required fields (`ISBLANK`) and out-of-range values.
- Provide data validation error messages explaining expected ranges to reduce back-and-forth with users.
- Recommend enabling the Excel Table totals row for quick sanity checks (sum of amounts, counts of components).
## Next Use
The consolidated tables above provide the authoritative field inventory required to draft CSV column layouts and Excel worksheet structures. They also surface validation ranges and metadata that must be preserved during import/export.
