In which step and which program the BDoc is created during Inbound process?

Hi,

I user middleware to replicate BP and BP Rel. I have a question regarding the inbound processing of BP Rel. During inbound processing, when system process IDocs, the BDocs should be created and processed by system. The function CRMXIF_PARTNER_REL_SAVE will called to process data.

So do you know in which step and in which program the BDocs will be created and saved into system?

Best regards,

Long
