I am trying to add the field 'CHARG' to the Layout of the tabstrip 'Purchase Order History' in transaction ME23N.
I think I should use the BADI ME_POHIST_DISP_CUST , with mehtod IF_EX_ME_POHIST_DISP_CUST~FIELDCAT_CHANGE
but I don't know how to do this.
Is it possible to add a field to the fieldcatalog?
Thanks in advance.
