Hi,
I remember that there should be a way for this
1 pass several item codes as one string to a subreport
2 from the subreport, we verify each item code in that string and return an error message for any invalid one
(I remember that we can verify that through the formulas. Am I right?)
One thing more is:
it should be possible to further put each item code as one column header in that subreport, shouldn't it?
