To make custom fields created at the Sales Order item level flow to the Purchase Requisition (PR) and Purchase Order (PO) item levels in SAP S/4HANA Public Edition, you need to follow these steps:
1. Create Custom Fields:
Ensure you have already created the custom fields in the Sales Order item level using the "Custom Fields and Logic" app.
2. Enable Custom Fields for Relevant Business Contexts:
You need to enable these custom fields for the relevant business contexts like Purchase Requisition and Purchase Order. If these contexts are not available in the "Custom Fields and Logic" app, you might need to use different tools or steps to achieve this. Follow these sub-steps:
- Open the "Custom Fields and Logic" app.
- Navigate to the custom field you created for the Sales Order.
- Check if the business scenarios related to Purchase Requisition and Purchase Order are available. If they are not, proceed to the next steps.
3. Extend the Data Model:
Use the "Custom Logic" and "Data Source Extensions" apps to extend the data model so that custom fields can flow through the process chain. You can use BAdIs (Business Add-Ins) to populate custom fields in subsequent documents.
4. Use BAdIs for Custom Field Mapping:
Implement relevant BAdIs to map the custom fields from the Sales Order to the Purchase Requisition and Purchase Order. Common BAdIs used for this purpose include:
- BAdI for Purchase Requisition:
Implement the BAdI ME_REQ_ITEM_CUST_FIELDS to add custom fields to the Purchase Requisition item level. - BAdI for Purchase Order:
Implement the BAdI ME_PROCESS_PO_CUST to add custom fields to the Purchase Order item level.
