rsa7 - a lot of entries

Hi, I have been contacted by basis that we have enormous numbers of entries in rsa7:

0BP_BANK_ATTR    IWP800    423.746

0BPARTNER_ATTR    IWP800    187.017

Even delta is schedulled on daily basis

I have done successfull delta 2 times :

0BP_BANK_ATTR  830 and 2 entries

0BPARTNER_ATTR 840 and 1 entries

This should clear the RSA7 as it is recomanded way how to clar the queue prior upgrade etc.

But I still have

0BP_BANK_ATTR    IWP800    423.749

0BPARTNER_ATTR    IWP800    187.020

Any idea why?
