How To Fix GU980 - The target table already contains data -> Read long text

GU980 - Overview

• Message type: E = Error

• Message class: GU - FI-SL utilities

• Message number: 980

• Message text: The target table already contains data -> Read long text

What causes this issue?

Since the target table already contains data (possibly in a different
client), any subsequent changes made to the field movements for the
conversion could result in inconsistencies between the summary table
that has already been converted and the control tables and line item
tables that still have to be converted.

System Response

For this reason, you can only display the conversion field movements
for both of these tables.

How to fix this error?

If subsequent changes are essential, you must first delete the
transaction data in the target table.
If necessary, the entire conversion must be repeated.
