Please tell me in The Solution-manager i.e in the report
hOW TO GIVE THE PARAMETER AS SELECT-OPTION AND RUN THE TRANSACTION TO GET THE DETAILS MULTIPLES.
Before making a z-copy of the standard report analyze it whether the data you are interested it are somehow accessible from outside (e.g. when they are exported to the ABAP memory).
If so then you can write a simple report having just the selection-screen of the standard report (parameter replaced by select-option).
Within this frame report you LOOP over the new select-option and call the standard report via SUBMIT... AND RETURN.
You collect the returned data for each run and afterwards gather the data together.
