Diagnosis
The field name with the name &v2& was used for a DataSource field.

System Response
If possible, you should not keep the field name because it is reserved.

Procedure

• If the DataSource is newly created or if no data was yet loaded, change
the field name. Note that you must make the change in the source systemfor DataSources from SAP or BI source systems (replicating sourcesystems).

• If the DataSource is already active and you do not detect any problems,
you can keep the field name. However, we cannot guarantee that allfuture applications will work without errors.
Note that problems might only occur when the DataSource is used in a BIsystem with a different database, particularly for transports and BIContent delivery.

Procedure for System Administration
You can find the reserved field names in the DB table TRESE.
