SAP Message XW257 - Cannot clear table &1

Diagnosis
Table &V1& contains invalid entries and cannot be cleared at this time.
This situation can only happen if some data was stored in table &V1&after the start of the job. Extraction jobs always clear table &V1&at the beginning of the run. However, during the processing of aparticular segment, table &V1& cannot be cleared for technicalreasons.

System Response
Processing continues, but application server memory is used instead oftable TXW_INDEX. This may lead to memory shortages at a later timeduring this job.

Procedure
There is no particular action necessary. If the job fails, thenrestarting the job should clear table &V1& .
