Customer Name validation AL

Posted on by Romryan

Hi all,

I need to validate customer name during creation of a new customer such that the creator must enter at least two strings i.e., you should not enter one name but at least two separated by a space.

How can I achieve this in OnAfterValidate or OnBeforeValidate trigger?

Hi Romryan,

have a look at String Functions.

You could use strpos to get the position of a space, and then check if it's not at the first or last index of the string. (maxstrlen)

You can try the below code

[EventSubscriber(ObjectType::Table, Database::Customer, 'OnAfterValidateEvent', 'Name', false, false)]

local procedure OnAfterValidateEventName(var Rec: Record Customer; var xRec: Record Customer; CurrFieldNo: Integer)

var

SpacePos: Integer;

begin

SpacePos := StrPos(Rec.Name, ' ');

if SpacePos > 0 then

if CopyStr(Rec.Name, SpacePos + 1, MaxStrLen(Rec.Name)) <> '' then

exit;

Error('Please enter name with a space.');
