Hi Eli,
The Commitment item defined in the GL master data is valid and can be displayed with FMCIA. At the point of posting, system is able to derive it into the required field. But when I am about to save, the error message comes up with the internal number for the Commitment item. The commitment that the system prompts with the error is the ITEM(field name POSIT in table FMCI). I really don't know why the system is making reference to that.
Kind regards
