One quick question, I got some problem about feeding string.
My rule is
['Transfer Plan'] = S:
DB('Transfer by Month', !dim1, !dim2,STR(DB('Transfer by Unit', !dim1, !dim2, !GBL Project System ID, 'Transfer Period'),2,0), 'Period');
The rule returns correct value, unfortunately, when I trace feeders I is not fed.
Then I inserted FEEDSTRINGS at the first line of both cube (Transfer by Month and Transfer by Unit), but trace feeder still not fed

What should I do?
