SD->CRM Credit release status issue

My issue as follows,

The order released in ECC is not reflected correctly in CRM. When order is released through VKM3, Order will have released system status at header header level in ECC, but in CRM it will still have blocked system status at item level.

but other status were reflecting successfully in CRM like 1.  "Credit Check Not OK"-  if there was a credit block in ECC

2. "Completed/Completely Delivered" - if order was completed the billing, delivery & invoiced in ECC.

please need quick help.

Thanks
