I have WDA application that list schedule agreement headers in one ALV and when you select one the line items show in the second ALV2 below. We show quantity and net value in 13 monthly buckets beginning with the validity data. The function returns the month text in columns I want to change the header based on the months returned. So instead of QNTY1, QNTY2 it would be 01/2008, 01/2008 etc. But ALV2 is initialized when the page is built and if I change the ALV2 settings after the line item function call they are not updated. On the page. Is there anyway I can do this???
It tried put the code in the EXECUTE function method, and I tried WDMODIFYVIEW but the ALV is not refreshed.
Thanks
