How To Fix UD366 - The attributes of entity type & are inconsistent

SAP Error Message - Details

• Message type: E = Error

• Message class: UD - EDM - Enterprise Data Model

• Message number: 366

• Message text: The attributes of entity type & are inconsistent

What causes this issue?

Inconsistencies arose when checking the attributes of the entity type.
Two types of error message were distinguished:
"E" messages and "W" messages.
"E" messages refer to errors that must be eliminated saving the
attributes as otherwise they would lead to serious inconsistencies
(example: attribute names occur several times).
"W" messages refer to less serious errors that should if possible be
eliminated before implementation in the ABAP/4 Dictionary.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check the error messages in the log. Correct the errors described in
the"E" messages and, if necessary, also those described in the "W"
messages.
