DTS - Datamarts

Hi Gurus,

I have questions regarding psa tables using DTPS.

I load delta data from an DSO to 4 cubes via DTP.

Since its a daily delta load we expect more lines getting loaded and need to implement

some sort of PSA clean-up on a periodic basis.

Can anyone tell if the Datamart DSO>>Cube via DTPS does use any sort of PSA/Stagign tables

in the background which have to be maitained??

Answers will rewarded.

Thanks
