Hi,

I am new CRM area and will not some hints on where to check.

When the the Sales orders are successfully created in CRM, they are replicated to R/3 but the sales orders are not saved in CRMD_ORDERADM_H table of the CRM system.

Also, I dont know see any details of the sales order in the interaction record document flow.

Can you please help me with any hints on where to check to fix this issue..
