We have integrated Zoho Finance into Zoho CRM. In Zoho Books we have enabled the multiple transaction number series because we have different department. Until yesterday, we could choose the different department (multiple transaction number) as we create an estimate in Zoho CRM / Deal. Since today if we create a new estimate in Zoho CRM / Deal the standard transaction number serie is chosen and cannot be modified. 

in Zoho Books this is still possible:

How can we change it?

Currently, we are doing it in the Zoho Books, but then there is the problem that the estimate is not connected to the Deal anymore... it is connected to the company and connected to the contact but not to the deal in the Zoho CRM.
