Promo Activation - Issues related to performance

Hi,

The promotions which are created by the users are pretty big where in the promotion can have 1000's of articles in it..may be upto 5000 articles in one single promo..If we try to activate all articles in a promo using WAK5, we get the ABAP dump "TSV_TNEW_PAGE_ALLOC_FAILED". Does anyone of you have come across this error message and if so what was the solve?

Any help would be greatly appreciated

Thanks,

Srinivas
