SAP Error Message - Details

• Message type: E = Error

• Message class: MDG_MDF - Master Data: Messages

• Message number: 008

• Message text: Definition of Field &1 is inconsistent

What causes this issue?

The definition of the field &V1& in system with destination &V2& differs
from the definition in destination &V3&.
At least the property &V4& is different.

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?

Change the definition of the field in the corresponding system. When
doing so, first check the property &V4&. Note, there may also be
differences in other properties.
Another possibility is that property &V4& is not directly maintainable
in the definition of the field, but instead is calculated from multiple
other properties. Therefore, make sure you also check the entire
definition of the field.
If attributes are assigned to field &V1&, the time-dependency setting of
individual attributes must be the same for all destinations.
