Add external link
Event action – Abstract
Purpose: Adds the 'external link attribute' for a specific external link type to a related object, if not already present.
See also: Remove external link, External Links, External links (background)
The Externen Link hinzufügen event action adds an external link attribute with the External link type specified by the parameter to the attributes of the reference object, provided that no external link attribute with this type already exists.
If the reference object does not support external link attributes, an external link attribute with the specified External link type already exists, or no External link type is specified, nothing will happen.
By default, the business transaction object types (Allgemeines Geschäftsobjekt, Orders and Sendungen) can be used as reference objects, however, the Manifests cannot be used.
Configuration
The single, unnamed parameter specifies which 'External link' should be added by a static, unique selection from the dynamic enumeration External link type.
Since each external link type can be assigned to the same business object only once and the value of the attribute provides the External link type (externalLinkType) as the only field, it is also necessary to specify only the type to add it.
