The error message "Create not possible; source object inconsistent" is displayed in the UI.

The error message "Create not possible; source object inconsistent" is displayed when manually adding a Invoicing Unit in a Contract because a Invoice document has been already created and released for at least one of the Line items in the Contract document.

As the Invoicing Unit is defined whenever a Invoice document is created, a change in this party role could lead to inconsistencies and therefore the error message "Create not possible; source object inconsistent" is displayed as the system will not allow this change to be performed.

As changing the Invoicing Unit in a Contract Document will only be possible if non of the items maintained in the contract were invoiced or partially invoiced, then in order to perform this change it will be required to cancel any existing invoice document generated from the Contract.

Note: If non of the items maintained in the contract were invoiced or partially invoiced, then the adding the Invoicing Unit party role in the contract will be already possible.
