When IN-A opens and "Enable Opening List For IN-A" is set (Settings-US-A), it loads the "INVENTORY" grid.  Go to "Queries-SU-A" and edit the "INVENTORY" grid.  See if there are any "UDFX()" fileds.  If so, they may have been removed from the main \DBAMFG / EVOERP folder.  If this is the case, find these files ("UDF?.SRC") and put in main folder.  If in the INVENTORY grid, but can't find files, then remove from the grid until you figure out.

Ran SM-P-E, and that fixed it.
