Interdependant changes for sales order status

Hi,

In my scenario, sales order has been created in ECC and replicated in CRM. I want user should be allowed to change status of such replicated orders in CRM. Now system is not allowing as original document is in ECC. I have maintained below entries in tables.

Settings in CRM Enterprise: table SMOFPARSFA

Key: R3A_SALES

Parameter Name 1: INT_CHANGE_ORDER

Parameter Name 2: <sales document type>, for example TA

Parameter Value 1: A for activating the scenario for interdependent changes for <sales document type>

Parameter Value 2: A for activation of APO

§ Settings in the ERP system: Table CRMPAROLTP

Parameter Name: CRM_SCENARIO

Parameter Name 2: INT_CHANGE_ORDER

Parameter Name 3: <sales document type>, for example TA

Parameter Value: A for activating scenario A for <sales document type>

What else is required to be maitained to make sales order editable in CRM?

Regards,

Nikhil
