Hi I have requirement where i need to call a static attribute a Class (ZL_CRMCMP_B_BUPADETAILB2B_IMPL) to custom Function Module which has configured externally (configured by CRM functional resource instead of standard FM). So here i should need a GUID of a ZL_CRMCMP_B_BUPADETAILB2B_IMPL -> GUID(which has the current GUID) and i need to pass that value to the external FM. Pls help. I tried all the other options using Memory ID (Export and Import) but by the time from the navigation bar when i click on the save where the external FM calls but no value for GUID. Help me on how to retrieve the GUID (current) to get the instance of that class.
