Enhance ME23N Transaction to Enable Drill Down to Purchase Order Item

        Whenever you program ABAP reports displaying Purchase Order Items data it is nice to have drill down functionality to transaction data (trx. ME23N). It looks like a trivial task (setting Parameter IDs for Purchase Order / Item and Call Transaction), but in reality ME23N transaction is not using Parameter IDs as we expect. In my blog I will explain how to enhance ME23N to make drill down work.

          What is takes is to enhance INIT_TRANSACTION form in RM_MEPO_GUIF01 adding some code to end of the form implicit enhancement point.

    So now if I jump from my report setting BES and BSP Parameter IDs everything will work like a charm
