Sync System Email Templates to all companies.

Challenge / Problem: Maintaining email templates across multiple companies.

Descritpion: Dynamics AX makes use of email templates for various bits of functionality in Dynamics AX, including workflow notifications and alert notifications. If you are using workflow in multiple companies and want to keep the same workflow template across the board, it can be quite frustrating to have to make the same changes in every company. The following script/job in X++ will help sync all (or some) system email templates and their respective languages into every company in Dynamics AX.

Model Management: Tools – Eventing II (validateWrite)

Following up on my previous post on the use of Eventing for model management today’s post will demonstrate how to use eventing effectively on the validateWrite method of tables. This can be very useful for additional model specific data validation without overshadowing the original method.

In this example I will use the validateWrite of the PurchReqLine table.

Instructions

1. Create a new class e.g. MyPurchReqLineEventHandler

2. Create a new static method in this class e.g. public static void validateWritePurchReqLine(XppPrePostArgs _args)
3. In the class retrieve the current boolean return value so that you can take it into account: boolean ret = _args.getReturnValue();
4. Get the original PurchReqLine Table record so that you can use it in your logic: PurchReqLine line = _args.getThis();
5. Add your logic to the method taking into account the current return value e.g.
if (ret)
{
ret = purchReqLine.myField != “”;
}
6. Set the return value (either at the end of your method or within the if (ret) statement: _args.setReturnValue(ret);
