Problem:

When an IMS screen is generated in AMB, the GENMFS is successfully created, but the MFSGEN in MFE fails because it can't find the IMSCONFG file or user is not authorized to read the IMSCONFG file.

I/O ERROR 9/009 OPENING IMSCONFG   - Invalid directory or no authority

CHECK "IMSCFG" VARIABLE SETTING

Resolution:

The error occurs when the CONFIG folder is not found in the product folder location.  Without this folder the IMS step will fail in MFE.  The folder is created when the CICS option is installed with MFE and the folder is then used with both CICS and IMS screens.  If you don't install MFE-EE with the CICS option you don't get a default CONFIG folder in the product folder.

One workaround to this problem is to manually create the CONFIG folder in the product directory. Another possible solution would be to install MFE-EE and take the default to install CICS.
