There are a couple reasons why we cannot display "The Part/Revision typed in does not exist in the inventory tables" message rather than the current message we display "NO MRP records were located for the criteria Selected" when user enters in a part that DOES NOT exist within the inventory in the MRP Part Number Range Find feature.

 

1.  If we were to change the valid in the part number field the user would no longer be able to go to the Find screen and leave the part number field blank and just click on the OK button to display ALL of the parts.  Instead the user would get the message "The PartRevision typed in does not exist in the inventory tables" and no parts would be displayed. 

 

2.  Another reason is if the user would like to find all the parts within a range, say 100-0000000 to 199-9999999.  The part numbers at each end of the range might not exist, but the parts within the range would be displayed under the current system.
