ME2M adding a new column

Hi,

I have a requirement in which i have to add a new column to the output list of the ME2M txn. The values for that column come from the MBEW-VERPR field based on the MATNR.

How do i add this?

Should i create a Z program copy the existing standard TCODE program and modify it OR is there any user exit to do this. i managed to see the list of user exits in the TCODE but i dont know if they are useful or not.

Any suggestions?
