Copying Control for Sales document from a sales document

Dear Gurus,

for the subjected matter I have gone through many thread with the same issue but I cross check all the setting, its fine.

I have created quantity contract type ZQCM is the copy of CQ, and ZM01 order type is the copy of OR document type.

When I am creating sales order ZM01 with reference to ZQCM, system give me the following message.

Copying from sales document type ZQCM to ZM01 is not supported

Message no. V2004

I have cross check all the setting like copying control from sales document to sales docuement, where target is ZM01 and Source is ZQM is maintain same as CQ to OR.

Kindly suggest the solution.
