Requirement : I want to add current date and time stamp in the middle of the receiver file name using abap dynamic configuration functionality.
Step 1: Configure Receiver file communication channels like below.
Step 2 : click on Advanced tab and check adapter specific message attributes.
Step 3: Create mapping class in SE24.
Below is the sample code in mapping class.
Step 4: Assign mapping class at operation mapping level.
Step 5 : Provide our operation mapping details at Interface determination level.
Then output filename will be Test+Current date + time stamp + .csv.pgp
Hope this will be useful.
