SAP MDG · VALIDATION DERIVATION

How do I implement a blank or no-op DERIVE_ENTITY method in SAP MDG USMD_RULE_SERVICE?

Use a minimal IF_EX_USMD_RULE_SERVICE~DERIVE_ENTITY implementation that does nothing when no derivation is required. If you are creating the BAdI from scratch, define it in SE18, create the implementation in SE19, assign the implementing class, and activate the class skeleton.

SOLUTION SUMMARY · SHORT ANSWER

Use a minimal IF_EX_USMD_RULE_SERVICE~DERIVE_ENTITY implementation that does nothing when no derivation is required. If you are creating the BAdI from scratch, define it in SE18, create the implementation in SE19, assign the implementing class, and activate the class skeleton.

A minimal MDG derivation scaffold is enough when no defaulting is needed: implement `IF_EX_USMD_RULE_SERVICE~DERIVE_ENTITY` and leave the body empty. If you are starting from scratch, first verify the BAdI definition in SE18, then create the implementation in SE19, assign the class, and activate it.

Process flow

  1. Open SE18 and display BAdI `USMD_RULE_SERVICE`.
  2. Confirm the interface name is `IF_EX_USMD_RULE_SERVICE` and whether the BAdI is filter-dependent.
  3. Open SE19 and create the implementation.
  4. Enter the implementation name, short text, package, and transport request.
  5. Maintain filter values if required by the BAdI definition.
  6. Assign or create the implementing class.
  7. Implement `IF_EX_USMD_RULE_SERVICE~DERIVE_ENTITY` as a no-op if no derivation is needed.
  8. Activate the class and then activate the BAdI implementation.
