Key Features of SAP Purchasing Tcodes
1. Customizing (IMG) vs. Operational Tcodes
IMG Tcodes (Implementation Guide) are used to configure system behavior and master data setups. General Tcodes are used for executing daily operational tasks like purchase requisitions and RFQs.2. Integration with MM and FI
Most of these Tcodes directly affect Material Management (MM) and Financial Accounting (FI) modules, making them crucial for consistent procurement cycles and cost allocations.Best Practices for Using Purchasing Tcodes in SAP
- Segregate Roles: Ensure that customizing Tcodes (e.g., OME1, OMEC) are only accessible to SAP consultants or authorized personnel.
- Documentation: Always document changes made using IMG Tcodes to maintain auditability.
- Testing in Sandbox: Before applying changes to production, test new settings in the sandbox or QA environment.
- User Profiles: Use Tcodes like OMEI and OMEH to customize roles and limit access based on responsibilities.
