Assigning values to properties in property schemas

I hope I understand your question – you are asking how the basics of promoted fields, correct?

Make sure you are in a \”MessageAssignment\” shape – i.e. you are constructing a new message if you want to set the value of a message on the left of the equal sign.

msgout(TestSchema.PropertySchema.CustomerId) = msgin(TestSchema.PropertySchema.CustomerId);

If you just need to set a variable, you don’t need to be in a \”MessageAssignment\”:

myString = msgin(TestSchema.PropertySchema.CustomerId);

When you type the parentheses after the message-name, intellisense should give you a list of promoted fields. Just scroll down to your project’s namespace.

If you are using distinguished fields, the syntax is quite different:

msgout.CustomerId = msgin.CustomerId;

You might have to do a build once to get the intellisense to work.

You can also use the xpath statement as an alternative, so in this example if have a distinguished field on the left, but I’m using xpath on the right.

msgout.CustomerId = xpath(msgin,\”string(//Order/CustomerNumber)\”);

Xpath can also be used on the left side of the equals sign.
