ARDBCGetMultipleFields

Description

This function retrieves a list of fields from an external data source. The plug-in calls this function when the BMC Remedy AR System server receives an ARGetMultipleExtFieldCandidates API function from a client. For example, an BMC Remedy Developer Studio client might provide a user with a list of fields instead of requiring the user to enter a field name.

To test your ARDBC plug-in in a vendor form, you must implement ARDBCGetMultipleFields. If you do not implement this function, the Available Column fields in the Vendor form do not contain the name of your plug-in.

Important

If you do not define this function and the plug-in server receives a get multiple fields request, the BMC Remedy AR System server returns a list of zero fields.
