How the Grouping 0002 gets determined while creation of Contact Person in CRM WEBUI

Hi,

We have two groupings 0001 and 0002 in SPRO-Cross-Application Components-SAP Business Partner-Business Partner-Basic Settings-Define Groupings and Assign Number Ranges (Other groupings are meant for Customer,Employee,Org unit and Vendor and for this we have link with PIDE or in Intergaration table).

In 0001 and 0002, I have number range assigned to it.

When I create a contact in CRM WEBUI, system is creating contact with Internal number range and with the grouping 0002 (taking automatically). Pl help me to understand where this grouping 0002 is linked with Contact person.

Regards
