Sage 100

Sage 100 Advanced version 2014 PU 4. Each time I try to add a UDF to a table, I get the attached error when the system starts to update views? What might be causing this?

I call that Schrodinger's error.

It turned out that there was a record in the file pvxview.grp. The table only has 2 columns: a record ID and a value field. The second row in the table, record number 00000001, had a null value. That was causing the error. By deleting this record via DFDM, the process ran without error. Thank you @NicoleRonchetti for finding the cause. I owe you once a again.
