Extending custom table

Hello there.

I need to extend the Purchase Header table via extensions using AL.

I want to add a check when the end user modifies the Buy-from Vendor. I want to check the value of a custom field (what is standard with the status Field).

So I went around the events route.

I captured the events that get thrown when this happens and I found the

OnBeforeValidateEvent.

SO I created a codeunit . This even does not seem to do much for me because I can not pass a record to it, so I can not check the value of another field. Var POheader is not part of the event variables. Any ideas on how do I accomplish my requirement.

Codeunit 50000 "Mysubscriber"

{

[EventSubscriber(ObjectType::Table, 38, 'OnBeforeValidateEvent', 'Buy-from Vendor No.', true, true)]

Local procedure CheckContractno(Var poheader: record "Purchase Header")

begin

//my code here.

end;

}

RE: Extending custom table

Hello Armela,

The event you subscribed that will give you 3 parameters as below:

var Rec: Record "Purchase Header";

var xRec: Record "Purchase Header";

CurrFieldNo: Integer

So you can write your business logic based on these variables, even though if it's not meet your requirement then you have to subscribe other field that you have to check.

below are the code for your reference
