'Function not available to this responsibility' When Trying to Access Custom Form

Error Message:

"Function not available to this responsibility. Change Responsibilities or contact your System Administrator".

Reason:

• Missing entry for CUSTOM_TOP in default.env file. 
• In R12, CUSTOM_TOP should be defined under default.env in $INST_TOP/ora/10.1.2/forms/server directory

Solution:

1. Login to Linux server with APPLMGR manager user access.
2. Go to $INST_TOP/ora/10.1.2/forms/server directory.
   Ensure that your CUSTOM_TOP's are registered in the default.env file.
   This means , we should create an entry for environment variable CUSTOM_TOP (which contains physical path to your custom directory) like below in default.env file present under location .
   $INST_TOP/ora/10.1.2/forms/server directory.
    

3. For Example:

   APPL_TOP=/home/applmgr/PROD/apps/apps_st/appl
   CUSTOM_TOP=/home/applmgr/PROD/apps/apps_st/custom
    
4. Restart the middle tier services.
