What causes this issue?

The indicator "Subsequent settlement index" for the retrospective
compilation of statistics has not been maintained for supplier &V1&
belonging to purchasing organization &V2&.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Set the indicator <LS>Subsequent settlement index</> in the supplier
master record (Purchasing data).
Then carry out a recompilation of the statistical structure 'S111'.
The recompilation ensures that all pertinent purchasing documents will
be taken into account in the cumulative business volume statistics.
If you do not carry out this recompilation, the system will take into
account only those documents that already constituted the basis of the
previously existing cumulative business volume figures. You can view
these documents using the <LS>Detailed statement</> function.
