 Change / Update Behavior Locate this document in the navigation structure

The Change/Update Behavior field defines how this operation changes the business object data in the back-end system. There are three possible update types:

  • Type 1

Data transferred by request messages completely overwrites corresponding objects in the back-end system database. The back-end system expects a value for all elements that are found in the structure of the message type. This also applies to elements that are designated as optional in the message structure.

  • Type 2

Data transferred by request messages only overwrites objects in the back-end system database that are filled in the message structure, with the exception of list-type elements.

  • Type 3

The operation updates the database fields for a business object only if the corresponding elements are explicitly contained in the incoming request.
