Hi Experts,
In tcodes : ME21n and ME22n, i need to validate MATNR field while entering it at the item level.
When i do not know a MATNR, i will enter an OLD material#(BISMT) in place of MATNR, i need to validate it against MARA table and get the respective MATNR and fill it at PO line item.
I am unable to find a suitable BADI or Exit to do this.
Please tell me how do i do this?
Thanks
Dan
