SA-23610

Summary

After adding a column to an external table that Pega has a class mapped to, Obj-Save calls are failing.

Error Messages

Cannot save instance of class [Class]; it belongs to fully exposed table [Schema].[Table] in database [Database], but the instance has properties which do not correspond to columns: [Property]

Steps to Reproduce

Save an instance of [Class] through any activity.

Root Cause

As the node had not been restarted, the table metadata had not been reloaded, leading to the error.

Resolution

Here’s the explanation for the reported behavior:

When a change is made to the DB table structure, one must either restart all nodes or re-save the corresponding Data-Admin-DB-Table or Data-Admin-DB-Name instance on all nodes.
