CD: According to this status, transaction 'Create billing document' is not allowed.

Dear All,

We have the PM Service Order User Status "30 Approved by super user".

With this status I need to accept quotation (that creates automatically a sales order) and to forbid the creation of the sales invoice (VF01).

I have indicated the business transaction for the User Status "30 Approved by super user":

. Accept quotation (allowed), because I need to accept quotation and create automatically a sales order).

. Create billing document (forbidden).

However If I indicate "Create billing document (forbidden)" when I try to do the following path from the service order IW32 "Functions - Accept quotation"the system show the following message ..."According to this status, "Create billing document" is not allowed.

Someone can help? I need to Accept quotation but to forbid the billing document.

Cheers.
