Did you know that Inventory users can have multiple blank tags for the same SKU in Physical Inventory counting?

With Contributing Author: Norma Robertson

Are you entering more than one tag for the same item, and getting the error INV_DUPLICATE_COUNT_UPDATE upon the Save?
Inventory users can now have multiple blank tags for the same SKU in the Tag Counts Screen in Physical Inventory counting.

Due to the additional features of Recounting provided as part of 12.2.13, the use of multiple blank tags for the same SKU was restricted.  New code changes have been provided to make this requirement available again in your PI process.   Note: For serial controlled items, this will not be valid and the appropriate error should be thrown.
