SAP Error Message - Details

• Message type: E = Error

• Message class: USMD1 - Datenmodel

• Message number: 103

• Message text: Data model &1, entity type &2: Change of data element

What causes this issue?

The data element &V3& has been replaced by data element &V4&. The two
data elements have different technical properties, however.

System Response

If master data has already been stored in the relevant generated
database tables, there may be a loss of data if the tables are generated
again (if the technical length has been reduced by exchanging the data
elements, for example).

How to fix this error?

Check if there is already master data stored in the generated database
tables.
Check if exchanging the data elements changes the technical properties
(data type and length) such that there is a loss of data when the tables
are regenerated.
