Creating and Deleting Control Characteristic Associations with Parts
The following API structure table lists the API fields that are required to create or delete MIC associations with a Material specification (or Part) within the current version of SAP distribution targets.
ZRFC_MAINTAIN_MAT_SPEC
SAP does not provide any standard APIs to create/update/delete MIC associations with a Material specification (Transaction code: QS61). 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 5.0 & ECC 6.0). The RFC fails if there is a difference in the screens or screen-flows (if any in your SAP systems).
Although this ZRFC is not declared as “commit required”, 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.
