How To Fix GR707 - Variable & has been changed (regenerate report group)

SAP Error Message - Details

• Message type: E = Error

• Message class: GR - Report Writer

• Message number: 707

• Message text: Variable & has been changed (regenerate report group)

What causes this issue?

The variable &V1& has been changed since the last generation of the
report group. The current report definition and the generated Report
Writer programs thus no longer correspond with one another.

System Response

The Report Writer informs you of this situation each time you execute a
report.

How to fix this error?

In order to have the current report definition, generate the report
group. The generation is started either automatically when you start
the selection (if the "Generation not automatic" indicator is not set
for the report group) or manually using the Report Writer generation
function (<DS:TRAN.GR55>Execute report group</>).
Caution: During the generation the existing extracts for the report
group are deleted for technical reasons because the data structure of
these extracts is adjusted to the old generated programs.
If you still require the existing data extracts and it would cost you
too much time and trouble to recreate them, you should ignore this
message for the time being.
