Failed to "update table row". The item was not found.

Question asked by ms867 on Oct 16, 2017

I'm trying to edit the attributes of a feature class in a local FGDB in ArcGIS Pro.

I get the following error when typing values into the attribute table directly.

Failed to "update table row".
Item was not found.

If I try using the Calculate Field tool I get the following error.

ERROR 999999: Error executing function.
Cannot acquire a lock.
Cannot acquire a lock.
Failed to execute (CalculateField).

However, if I try to perform the same functions on the same feature class in ArcMap there are no errors. 


ArcGIS Pro version 2.0.1

ArcGIS Desktop version


Any help would be greatly appreciated.
