Business Partner not created in PPM by ALE

Hello

I have done the integration between HCM and standalone PPM system with the note 363187  and information from links below to create BP in PPM-

Integration of cProjects and HR - Product Lifecycle Management - SCN Wiki

PPM - HCM Integration with Business Partners

For ALE, I am doing this -

O - Update mode - Infotype: 1000,1002,1028

S - Update mode - Infotype: 1000,1002,1028

P - Insert mode - Infotype: 1000,1002,1028

O - Insert mode - Infotype: 1000,1001,1002,1028

S - Insert mode - Infotype: 1000,1001,1002, 1028

Central Person, Position and Org. Unit  with relationships are created in PPM. BP for Org. unit is created correctly. But, the BP for Person is not getting created in PPM. After checking RPM_EMPDATA, I only see the CP created but no BP, Username, Name assigned.

The IDOCS are in Green status. HRALX/HRAC is Active, OBPON=ON, PBHR=ON.

Any thoughts on why the BP is not getting created?

Also, does the BP related to the Person have to exist in HCM (if it is a valid HCM object) already as an object to successfuly create the BP in PPM?

Thank you
