Rejection reason not flowing from ECC to CRM.

Hi,

We have a scenario in which Sales Order gets created in ECC and replicates to CRM. In this order Items are non delivery items and are having milestone billing.

The Item may be rejected in ECC with rejection reason added in ECC system but this rejection reason is not flowing to CRM system.

Kindly help us in this regard

Thanks in advance,
