What is the best way attribute for Custom Event with new Custom Order

Hi @InfTomaPr I don’t believe you need any attributes. Especially if you want this information message to appear after each customer order is created. 
Would be different if you wanted to trigger on a modification to a specific attribute.

@InfTomaPr agree with @COVJAMIEB. You don’t need any attributes. Just make sure the event fires when new objects are created (INSERT) in CUSTOMER_ORDER_TAB. Then you have the message everytime a new CO is created

Anyways, since it seems that you wanna remind the users to add the Project ID. Normally Project ID is also defined as a code part and then you can enable mandatory preposting for customer order → then the system will require the Project ID in preposting before allowing for the CO to be released. Just an idea, not sure if it’s relevant for your usecase.
