> In cases where different data objects of key component groups of a BDEF derived type are to be assigned to the same key component group of the same entity, a direct assignment works without a syntax warning because the content is identical. A direct assignment is recommended (`...wa1_root-%tky = wa2_root-%tky ...`). The use of the `CORRESPONDING` operator is unnecessary and less performant. This is true, for example, for key component group assignments in the context of RAP response parameters failed and reported.

### Ensuring Data Consistency in a RAP Transaction
The [LUW](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenluw_glosry.htm) concept, which deals with the transfer of data from one consistent state to another, applies to applications using RAP. RAP transactions are integrated with the [SAP LUW](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abensap_luw_glosry.htm), which is a prerequisite for transactional consistency. RAP provides a standardized approach and rules ([RAP BO contract](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenrap_bo_contract_glosry.htm)) for the [RAP business object (BO)](https://help.sap.com/doc/abapdocu_cp_index_htm/CLOUD/en-US/index.htm?file=abenrap_bo_glosry.htm) runtime to ensure that the RAP transaction is correctly implemented, data inconsistencies are avoided, and the SAP LUW is successfully completed.
