Hi Elham,
Can you please check if someone has moved the person in SRM org structure after it has been replicated from HR, if this is the case in tcode BP> relationships you will not see the relationship with Org node?
Also, please check HR data for personal number. Infotype 0105 (with sub type 0001 and 0010) and infotype 006 are mandatory to create a successful BP, CP in SRM.
Another point, CP should have B208 relationship with userID. Please check in tables.
Regards,
Ravi Pachauri
