Modifying standard report RM06EL00(tcode: ME2L) with PR and RFQ data

Hi,

The requirement is to add few more fields to the existing layout

of standard report RM06EL00(ME2L). For this we had thought of

copying the std prog and modifying it, but I am not able to

locate the place where fieldcatalog is populated in the program.

It appears to be getting populated dynamically.

Please suggest if there is any possibility of doing this or if

anybody has faced such scenario...

Thanks.
