Error Handling

Returns error JSON if:

• Supplier not found (suggests alternatives)
• Product not found for any item
• Invalid date format
• Invalid amounts or quantities
• Database connection fails

Database Tables

Writes to 3 tables:

1. tbl_porder_txn - PO header
2. tbl_porder_item - Line items
3. tbl_porder_movement - Stock movement tracking

Document Number Format

PO numbers follow pattern: PO{YY}{MM}{NNNN}

• Example: PO25100036 = October 2025, PO #36

Business Rules

• Supplier must exist and be active (Status_i = 1)
• Products must exist in tbl_product_code
• Order date must be valid date format
• Quantities must be positive
• Amounts rounded to 2 decimal places
• Default tax rate: 6% (for purchase orders)
• PO status defaults to 'P' (Pending)
• Automatic calculation: SubTotal + Tax = GrandTotal

PO Status Values

• P: Pending (default)
• A: Approved
• C: Confirmed
• R: Received
• X: Cancelled
