How to make one field mandatory in Enterprise Portal -> Web Control

Using Ax2009.

In web control 'PurchReqTableInfo.ascx' I have to make one field mandatory(marked with red asterisk).

How can I make my field mandatory?

  • It might be too late, but in case someone reaches this thread, just add the property "Mandatory" set to true in the field(s) in the .ascx file, and that's it.
