How to update correctly a UDT at FORM_DATA_ADD
When adding an item marketing document, my add-on has to update a UDT with all the lines in the document.
I have placed the update of this UDT in the BeforeAction == false and ActionSuccess is true on et_FORM_ADD_DATE.
But what if an error message appears when updating this UDT, how can I prevent that the document is not added in SBO either. If the update of the UDT fails for any reason I don't want to let the user to update the UDT.
What is the best practice in this case?
even if you happen to know at the before action true event that the update process generates an errror, you will not be able to roll back ( or make bubble event false) the actual document creation . it is going to happen anyway .
or you are getting at something else?
