Hi,

Can anyone help me with the code that I should write if I want to enter a value in a field in the General Journal form (External Document No.) at the moment when I enter a certain value Applies-to Doc. No. field. I have tried adding code in Applies-to Doc. No. - On Lookup trigger in Gen Journal Table but it didn’t work.

Thanks a lot.

Is this the right code?

Applies-to Doc No. - OnValidate

VALIDATE(“External Document No.”,“Applies-to Doc. No.”);
