BIP 11.1.1.7.1: Group Filters

Hello,

I have a data model with the following structure:

G_1

    G_2

The parent group G_1 record can have multiple child records in G_2.

I have defined a PLSQL Group Filter on G_1 but it seems that BIP executes it as many times as there are number of records in G_2.

That surprised me. I would have thought that since the filter is defined at G_1 level, it will only be executed for each row retrieved at G_1 level to either include it or not based on the filter outcome.

Is this how it's supposed to work?

Thanks,

Manish
