Too many rows for the entry screen in Planning Layout for TPM

Hi All

i'm responsible for the integration BW-BPS/CRM in a Trade Promotion Management project.

I found a problem due to the probable limitation of the planning layouts provided for TPM. To be more exact the high number of product inserted in a Trade Promotion causes the following error in the DHTML "Too many rows for the entry screen".

Anyone knows if there are thechnical constraints about that or any workaround to bypass the problem?

Thanks a lot

Bye
