TSV_TNEW_PAGE_ALLOC_FAILED* - No more storage space available for extending

Hi

Im loading data from one DSO1 to DSO3. While loading im doing LOOKUP for ZDATE infoobject which is avialbe in DSO2.

SO i written the code in "EndRoutine" . I called all the data from DSO2 into ITAB Internal table and the processing in the "EndRoutine" and then populating the data into ZDATE in the transformations between DSO1 -> DSO3.

But im getting shortdump during dataloading TSV_TNEW_PAGE_ALLOC_FAILED - No more storage space available for extending an internal table.

So how can i make internal table size more. I mean memory space if internal table.

Regards
