Changing or Deleting Control Characteristic Links With Operations
The following API structure table lists the API fields that are required to create/change/delete MIC associations with Routing operations within the current version of SAP distribution targets.
ZRFC_MAINTAIN_MAT_SPEC
SAP does not provide any standard APIs to create/change/delete MIC associations with Routing operations (Transaction code: CA02). This custom RFC has been developed using the BDC method provided by SAP, which records the screen and its' fields, which are used to fill the values on the screen.
* 
This custom-RFC is developed and tested in standard SAP IDES system instances (ECC 6.0, ECC 6.06, ECC6.07, and ECC6.08). The RFC fails if there is a difference in the screens or screen-flows (if any in your SAP systems).
Although this BAPI is not declared as “commit required” by SAP, from external system for multi threading mode, it is required to call BAPI_TRANSACTION_COMMIT to end the session otherwise locking errors may occur.
Further details on the RFC can be seen at the RFC DOCUMENTATION.
