CRM document replicated to ECC. But not able to edit

Dear Experts,

We are replicating debit memo request to ECC system from CRM. But when i am trying to edit the document in VA02, its not allowing me to edit. Am getting the below error.

Process the original document in the CRM system
Message no. V4310

Hope there is some setting required in Middleware parameter. If anyone having idea please share to me.

Regards,
Anandhan
