How to fix this error?

Check that you really do wish to change the "actual" data of version
'000' and whether the data on the selection screen is correct.
Since you have requested recompilation of the update data, it is
essential that you first delete the data for the relevant rebate
arrangements in version '000'. Under certain circumstances, multiple
updating of supplier business volumes is otherwise liable to occur.
Before you delete the data for version '000', you should carry out a
data backup.
SAP recommends the following procedure:
First carry out a check run. This will enable you to determine and
rectify all errors.
You should initially compile the supplier business volumes under a
version number beginning with the characters '&('. The third character
is optional.
Be sure to take note of the messages in the list output. Remedy their
causes and post the data of the affected rebate arrangements and
purchasing documents.
After successful compilation, copy the data into version '000' using
report 'RMCVISCP' or the Copy Management Tool of the Logistics
Information System.
