Posted on by fherrscher

I want to add a field in a sales order that is mandatory when posting it. It should only be allow to post if the field is not empty. Solutions like ShowMandatory or NotBlank are not an option.
I think I need a CodeUnit for that - or is there another way?

You need a codeunit to subscribe to the event OnBeforePostSalesDoc of Codeunit 80 Sales-Post

add your condition to check whether the field is filled or not and throw error if not.

You can try this....

IF Rec."field Name"=' ' THEN// Single Quotation Marks without space.

ERROR('Enter value for the field ');

else

...

//code when the field is not empty.

;

Add the above code in trigger OnAction of Post button.

Hope this helps.
