Find First/Last Failed for table Alt-PartTran (565)

Vantage 6.10.535
Progress 9.1D

I have an end user who inadvertently checked off Shipped in the
Packing Slip form. Unfortunately, the part was not shipped and every
time I uncheck the box. I get error listed in the Subject Header.

Has anyone encountered this problem before and can anyone recommend a
solution?

Thanks in advance,

Jose
