Deleting a User-Defined Function Link

The User-Defined Function Links functionality enables you to define your own Function Links based on data values held by variables in other functions.

To delete a User-Defined Function Link, follow these steps:

Add a GLOBAL_LSCALL that calls the @VIPDeleteUserLinkage Global Function to a function (an Update Function, for example).
Click Global Interface Mapping icon on the Logic Editor toolbar to open the Map Maintenance window. Click here to view an example screenshot.
Enter the relevant details for the @VIPDeleteUserLinkage Global Function parameters into the Map To fields using the following table as a guide.
