When creating a Purchase Order and adding a Freehand Item or selecting a Product, the system will automatically populate the default Nominal Ledger, Cost Centre, and Department codes based on the supplier's settings defined in the supplier rules.

These default codes ensure consistency and accuracy in categorizing the purchased items. However, if the default supplier codes do not match the specific requirements of the product, you have the flexibility to manually change them.

In cases where you have assigned Nominal Ledger, Cost Centre, and Department codes on a per-product basis, the system will prioritize these specific codes over the supplier's default codes.

Only when a product does not have any assigned codes will the system revert to using the supplier's default codes. This allows for customization and precise allocation of financial data associated with each product.
