BP numbers not created automatically for org units

Hi Experts,

When you create organizational units in Org. model transaction, business partners numbers are not created automatically ?

How can I do that without running transaction crm_om_bp_integrate

I have already setup:

Step 1: Defining Number Range for Org Business Partners

Step 2: Defining Groupings for Org Business Partners

Step 3: Set up integration

hralx-hrac - x

hralx-obpon - on

hralx-onumb - 2

hralx-osubg - Enter your Number Range defined in the previous steps here

save your entries.

Am I missing something else ?

regards,
