ADC error proofing in sage X3 - AIAG Standard Label

The automotive industry requires a unique identifier to guide a scan into the correct field in sage.  Our IT department has been unable to get the unique identifier to "strip off" at the indicator at the right point between the scanner and sage.  As a result, the user has to ensure that they are in the correct field in sage before scanning.    Does anyone have experience with automotive manufacturing in sage and scanning of materials?   Any ideas for error proofing the receiving process if we can't use unique identifiers?  

We are using the Honeywell CK75 scanner and sage X3 version 9. 

Example: (k) should guide the scan to the purchase order field, (p) should guide the scan to the part number field.
