[User Exit] CMOD, SMOD

User exit in sap tcode

CMOD: This transaction helps you to create a PROJECT by defining the ENHANCEMENT(s) of the transaction. You will need to enable the PROJECT after evaluating all the Upgrades that are part of the PROJECT. You will also need to code your user exit; hence, you may want to wait until this phase is completed before the PROJECT is enabled.

 

SMOD: This transaction facilitates the development, by defining your COMPONENT(s), of an ENHANCEMENT that will be included within the Project. If SAP has already created an ENHANCEMENT for its predefined user exits, you do not need to use the SMOD transaction; instead, you can only use the CMOD transaction.
