OO ALV dump - GETWA_NOT_ASSIGNED
I have implemented OO ALV to display data. Two of the fields are WERKS and MATNR. These fields are input enabled. I have not coded any F4 routine, the standard search helps work. I have SAP GUI 720 installed on my laptop and the program runs just fine. But when I try to run it on another machine with GUI 710 the search help function does not work and I get the dump GETWA_NOT_ASSIGNED. I may be wrong but it seems like there is a problem with the GUI version. Where should I check?
Thanks in advance,
