manufacturer missing in Sales Order Template

manufacturer missing in Sales Order Template

Hello Zoho, 

There is a manufacturer by default added to Items. 
1. First of all we want this field to be made mandatory which is not happening. 
2. This same manufacturer does not appear when created Sales Order, and there is not way that it can be edited from template to show on Prints of SO. 

As of now we have added the Custom Field but that is not going to work for longer period of time. 
Any solution?
