Org unit BP number not generated :(

Dear Experts,

I had configured the below settings but failed in generating bp umbers while creating org units.

1. Define Number Ranges

2.Define Groupings and Assign Number Ranges

3. Set Up Integration with Organizational Management

4. Now, created org units in ppoma_crm, but bp numbers are not being created.

5. Executed 'HRBCI_ATTRIBUTES_BUFFER_UPDATE'. Its fine.

6. Executed 'HRALXSYNC'. Here I selected the org unit and click on Start Repair.  Then system is throwing error message, that is "Grouping Z3 does not exist"

Please help me what needs to be done to generate org unit bp number from specific number range.

Regards,

Maddy
