ABAP - Ways To Retreive The Deleted Report Program.

check in table VRSD if there is an entry with OBJTYPE = 'REPS' and OBJNAME = name of the deleted program.

If yes, then create a new program in SE80 with the exact same name and revert to the previous version using version management.

If the program is there in the table then you can create a new program with the same name , and activate it and get the older version of the program . this can be done only if you saved the program under a particular package only . There is no case in getting the programs which are saved under the local object once it got deleted.
