SAP BPC 10 NW DM export transactional data package slow periodic measures

Hi,

We are running BPC 10 NW SP 8 CMB 801 NW 7.3 EHP 1

EPM Client 10 SP 13 patch 5 .Net4 Big Vol

We are experiencing slow performance when extracting Periodic transactional data to a flat file on YTD Model.

The package process chain is /CMP/EXPORT_TD_TO_FILE

There is about 14k records that we are trying to export, and it runs for over 2 hours without completing, When we select Measures : Periodic only

When we select Measures YTD , the package takes 15 sec's  to complete.

Any assistance would be appreciated

Regards

Gavin
