In a previous lesson, Jayson Butler, the sales manager at OEC Computers, asked Emily to make changes so that whenever a sales employee creates a sales quotation, they must enter the customer reference number.
Emily has already extended the Sales Quotation Detail view in the Web client and now she needs to add a validation on the Customer Reference Number system field. This way, the sales employee can only create a sales quotation if this field contains a value.


This scenario uses the same source code sample that we reviewed in the previous lesson. If you don’t already have the source code sample opened, you can open it here: Sales Assist App Sample.
