Set the System Code and Save
For a Release 18.104.22.168 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.
