Filter conditions for custom criteria in segment builder.

Hi Experts

I am using Infoset and data source to build the Target Groups in segment builder. in Infoset I am using joins between BUT000 and some custom tables , in which attributes are used in segment builder to calculate Target group.

I wanted create new filter conditions for below criteria  in segment builder.

1. The BP does not have Activity at all

2. The BP  does not have Activity from specific date

Table: CRMD_ORDER_INDEX returns the list of Header GUID of Activity by inputing BP number. But i need  All the BPs(Activity Partner) which are not been used for Activity creation yet.

Which table i have to use in infoset ? or is there any other approach other than infoset for these criteria in segment builder.
