BOM object down

Hello ,

We downloaded BOM object , BOMs were created in CRM successfully,

I also can see BOM object in trn R3AC4 (delta load), but BOM changes in ECC6 are not replicated automatically to CRM. If I am creating a request and start it data is replicated.

Is there smth else that I need to do to set up "delta" load of BOMS?

Thank you ,

Rika
