R47011 - Inbound Edit/Update UBE - Cross Ref (SZCITM)

Documentation states:

Only one of the item number fields has to be populated, but any fields populated are validated. Also, if CITM is populated with the customer's item number, it must be preceded by the symbol to identify it as a customer item number. This symbol can be located in the branch plant constants. In other words, if the symbol to identify a customer item number is # and the customer sends their item number 3003, CITM must be populated as #3003. In addition, the customer cross-reference (P41040) needs to be set up.

Issue: When populating CITM in the F47012 with customer item number preceded by symbol '#' defined in the Branch Plant Constants 'Invalid Item Number' error occurs even though Branch Plant Constant is properly set up and F4104 Item Cross Reference is properly set up. This problem occurs intermittently; not continuously or steadily.
