When using PAK messages shown twice

Hello Gurus,

We are in 7.4 SP12, using PAK.

In my cube there are 33 records with all KF = 0 and 2 records with KF <> 0.

I have a simple PLS (with FOX) performing some validations.

If I execute the sequence I see messages twice with different parameters:

I expect to see only "2 records read, 0 generated, 0 changed, 0 deleted" instead of 35 records read ...

If I execute the sequence in ABAP (with trace or setting PAK off) I see as expected "2 records read, 0 generated, 0 changed, 0 deleted".

I'm confused - what "realy" happens? 35 records read or 2 records read?

It is important for me because I don't want exmpty records to be read (as it is in ABAP execution) .

Thank you,
