I need to display material (MATNR) field in FB01 in line items, I have made the MATNR as 'opt. entry' from 'suppress' in OB41 against the posting key 31 (Vendor Invoice) but still the line item doesn't display the matnr field.
I also tried to maintain special variants in O7R3 but still no use.
Give some inputs on this.
Thanks in advance.
