Me again, I have to change a customer id for customer name into an ALV list but when I change this
read table e01_lt_fieldcat into ls_fieldcat with key fieldname = 'CLIFI' tabname = 'T_POS'. ls_fieldcat-seltext_l = 'ClienteFin'. sy_index = sy-tabix. modify e01_lt_fieldcat index sy_index from ls_fieldcat.
when I change CLIFI (customer ID) for NOMCLIFI (Customer name) the error TABLE_INVALID_INDEX appears. I will appreciate it any info, because it's an urgent specification.
Thanks in advance!!!
P.D. SAP version is 4.0B
