new object type in configuration tab

hi all

we have requirement to include the sap fiori apps in the configuration tab. since we can't directly include the fiori apps. we thought to integrate the back end event publisher from the transaction /IWFND/MAINT_SERVICE . ex for PO tracking -  ZSRA020_PO_TRACKING_MDL. these service name should be integrated in configuration tab.

ex : for IMG objects - COBJ is the object type defined in the configuration tab .  so my question is  how to find out the object type in the managed  system . is their any tables available in managed or solman system ?

second question : how to add the new object type from the configuration tab

Thanks

Sol man
