Step 1: Enable Online validation

See Online Validation to enable online validation.

Step 2: Add "Mobile Document Type"

Make sure a document type exists and points to a processing codeunit.

Pleas use (or take inspiration from) Codeunit 6181379 "MOB WMS Whse. Inquiry"

Press the "Groups" action and add the new type to the relevant groups.

Failing to do so will result in the following error:

Edit your processing codeunit.

MobBaseToolbox.CreateSimpleResponse(XMLResultDoc,'OK');

ERROR(MobWmsLanguage.GetMessage('UNKNOWN_LOT'),LotNumber);
