Adapter function [fConnect] failed (FDM)

adapter function fails in freshly-upgraded FDM application


Prerequisite: Fully functional Financial Consolidation application to which to connect.
Select Tools > Clear Error Log
Begin by selecting Metadata > Control Tables
Click Ok on any messages
Click in a cell under Target Year; If values are returned, the connection to an HFM application is active.
Otherwise select Tools > View Error Log
Use the output to identify the issue.
The number of active custom dimensions in the FDM Adapter must match the number of custom dimensions in the HFM application
Connect to Oracle Hyperion FDM Workbench
Expand the Dimensions of the Target System Adapter
Right-Click Custom1 and check Active
Repeat for Custom2, Custom3, Custom4
Set the System Code and Save


For a Release Financial Data Quality Management application, an error may occur like Unable to retrieve target System Data. The error log often facilitates identification of the connectivity issue. For example, “ActiveX component can’t create object: ‘fdmFM11xG5B.clsFMAdapter'” might indicate the System Code should be changed from FM11x-G5-B to FM11x-G6-A for HFM connectivity.
An error like Adapter function [fConnect] failed might indicate the number of dimensions Active in the adapter does not match the number of custom dimensions in the HFM application.

      Vijay, is this a production application?
      Was it working before or are you trying to get it working for the first time?
      What is the version of FDM?
      What target application(s) (e.g., HFM, Essbase, …)
      Is there a source system type & version (ERPi?)
      Thank you,

        Hello John/Vijay,
        We too are facing the same error and this is a production environment.
        Previously this was working fine but now we are facing this challenge regularly..
        HFM & FDM version.

        When ever i am facing this error, i am re configuring the adapters (just provide username & password) and it was working fine but after some days it goes back…

        Thanks in advance..
