How To Fix AD188 - Technical settings for table & have been deleted

SAP Error Message - Details

• Message type: E = Error

• Message class: AD - Data Dictionary application messages

• Message number: 188

• Message text: Technical settings for table & have been deleted

What causes this issue?

The technical settings determine how a table is defined in the
database. They are only relevant for transparent tables, since
structures have no physical equivalent in the database and, in the case
of pooled and cluster tables, it is the table pool or table cluster
assigned to the table that decides how the data is stored in the
database.
The technical settings for the specified table are no longer required
and have, therefore, been deleted.

System Response

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