Hi Experts,
We are stuck with cancelling a sales order. This sales order has more than 20K line items on it and when rejecting, the system errors out in ST22. We tried directly from VA02 as well as using a custom program that calls the BAPI to reject the document in BG mode, but no luck. Both the cases, system fails to cancel this bill and logs a dump in ST22. The details of the error is TSV_TNEW_PAGE_ALLOC_FAILED ,
No more storage space available for extending an internal table.
You attempted to extend an internal table, but the required space was
not available.
We checked with the basis administrators but it seems the time out and memory parameters are set to the maximum.
Can any one suggests how this can be tackled and some how reject this gigantic bill 
???
Thanks,
Dhan
