Client Requirement =>
When we have made the MRN and Save, Total amount not showing. Should be show MRN total amount/print preview.
Apparently we had same requirement from Client, but somehow I managed to convinced on receipt Amount is not possible. ( In case you are not fine with Form personalization)
You can see total amount on Purchase order form or Purchase order Invoice as there is no option available to Amount on receipt .
( Amount = USP*QTY I am assuming).
Or can create custom report with MRN with total Amount.
