Pharmacy Module Development Guide

Key Documentation

For detailed pharmacy development, refer to these files:

Pharmaceutical Management API - REST API for managing VTM, ATM, VMP, AMP, VMPP, AMPP, categories, dosage forms, and measurement units
GRN Fixes - GRN completion patterns
Multi-Window Sales - Multi-window handling
Cost Accounting Signs - Sign normalization
Disbursement Signs - Disbursement conventions
Quantity Decimals - Decimal validation
Transfer Disbursement - Transfer workflow
Purchase Order Workflow - PO workflow

Configuration Options

Pharmacy uses configOptionApplicationController.getBooleanValueByKey() for feature toggles. Key patterns:

Pharmacy Transfer is by Purchase Rate / Cost Rate / Retail Rate
Display Colours for Stock Autocomplete Items
Pharmacy Disbursement Reports - Display * (various column visibility)

Common Patterns

Stock Queries

Always include s.retired = false and s.itemBatch.item.retired = false
Filter inactive items with s.itemBatch.item.inactive = false
Use DTOs for display, entities for business logic

Transfer Workflow

Transfer Request -> Transfer Issue -> Transfer Receive
Each step creates a Bill with appropriate BillType
Sign conventions matter for cost accounting

Retail Sale

Use StockDTO for autocomplete performance
Cache autocomplete results for converter
Defer expensive discount calculations

Backward Compatibility

Never "fix" purcahseRate spelling - it's a database column name
Never rename composite components without checking ALL usage
