Quick Solution::
Add Application Root Folder and Save.

Read below for Problem Summary.

Importing ERP data into Target Hyperion Planning or Essbase Application is primary usage of FDM Application setup.

There are sometimes small elements which we might ignore, and lead to unprecedented errors. One such error occurs, while importing Data after initializing the Source system.

This error comes after ODI fetches data from source system, and puts this data in the FDM Staging Table.

The error is because of the absence of FDM Application root directory, which has inbox/outbox folders, which will be used to store the Flat file to be imported into Essbase.

Error Summary:

FDMEE Data extraction Error
The Value for Profile option ‘PROFILE_APP_ROOT_DIRECTORY’ is invalid: NULL 

‘PROFILE_APP_ROOT_DIRECTORY’ is invalid: NULL, 683 FATAL [AIF]: Error in COMM Pre Import Data
