MDG mata data error: No catalog showing for UI Configuration

Hello Experts,

We are getting below error:

Error in MP: The metadata definition of node 'ZPA_GLOB ' (ABBID: MDG_MAT ) is insufficient - node data type missing (termination: RABAX_STATE)

We have created an Entity 'ZPA_GLOB'. Structures are created and visible in MDB. But when we try to configure this entity on UI, it gives error Feeder class does not provide a valid catalog.

We have used standard feeder class. (CL_MDG_MAT_FEEDER_FORM).

Kindly advise if we are missing any configuration which is causing this error.
