Altering the source expression on a request page field

Posted on by Microsoft Employee

Hey all, 

I'm working on a custom report has a request page. 

On the request page I enter Order No. the next field below it on the request page is Contact No.

When I enter the Order No. the contact number defaults. How can I control that default?

For example: Order No. 3 has the location-contact: Rob contact ID 01 and the owner-contact: Zach contact ID 02.

I run the report and enter in order 3 on the request page, the field below it auto populates Zach contact ID 02 the owner-contact. My goal is to enter the order number on the first field and have the location-contact Rob show up. 

The report is built on a single dataItem Contact. In order to distinguish owner-contact from location-contact I'll need to use the Customer table. 

Looking at the properties of the request page field that i'd like to auto populate:

SourceExpre = VAR_ContactFilter
TableRelation: Contact.No.

Could I join Contact (the reports dataitem) to Customer on the tableRelation property of a Request Page?

What are other options for automating a fields value?

I'd be happy to explain further. Thanks so much.

    Ah , thank you.

    To be clear, I need to create a Global Variable something like VAR_DesiredContact and define that variable within the C/AL code assigning it the contact I want.

    Then I set it as the sourceExpression variable for that field on the request page?

    I'm looking for an existing variable that behaves like that to use as a template now.

    you need to create a variable in report and calculate the contact from order and assign the value to variable.

    set variable in contact sourceexpression instead of
