Application layer: The actual execution of the command is done in this layer. All commands given at presentation layer are passed to application layer where work processes will look after the execution.
Database layer: This is most bottom layer of SAP R/3. Extraction of data from the database and insertion of data into database is done at this layer.

I am trying to automate a manual processing of iDOCs in BD87. I used the following code to pass idoc-id to global variable 'DCN' and then skip the first screen of BD87 to go to processing directly. After running this code SET PARAMETER ID 'DCN' FIELD itabhdr-idoc_id. CALL TRANSACTION 'BD87' AND SKIP FIRST SCREEN. it takes me to the first screen because it cannot recognize my idoc-id. How I can pass idoc-id to global? I have used the above code to goto VA02 with VBELN and it worked perfectly.
