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
