Hi,
By assigning commitment item to G/L in G/L master data, you can further define the rule in FMDERIVE which will fetch this information from G/L, while introducing commitment item. Of course, you can manage it in another way and make a rule in FMDERIVE, based on Table lookup, maintaining all combinations of GL-CI, but that's less efficient. Just remember, that linking CI to GL doesn't imply automatic derivation of this CI: you have to tell FMDERIVE to do so via a rule.

Eli
P.S. Thank you for promoting my new book!
