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?

You can correct the faulty update by carrying out a recompilation of
the statistics or by carrying out a business volume comparison and
agreement process.
Please check whether a new price determination process was carried out
after the updating of the LIS statistics relating to "subsequent
settlement" with respect to purchase order no. &V1&, item &V2&. As a
result, the pricing types may have been changed or the exclusion of
conditions relating to "subsequent settlement" activated.
