A Domain's Parameter ID and its Default Component Name?
Can someone tell me what these are used for?
Domain's parameter ID is the same ID that is used when we do CALL TRANSACTION. This ID helps in assigning values to the fields to which the values need to be passed when we call a transaction throught ABAP Code.
Default component Name is used in Infosystem to classify and arrange them in a logical module . Thie helps in error resolution and finding help in SAP Service Marketplace and OSS Notes.
Hope this clears
