• Message number: 116

• Message text: For table &1, no TABCLASS has been specified in DMC_MT_TABLES!

What causes this issue?

For table &SYST-MSBV1&<(>&<)>SYST-MSGV1<(>&<)> there is no entry
TABCLASS in the table
DMC_MT_TABLES. Therefore it cannot be determined whether this table
is a transparent, a pool- or a cluster-table. So no runtime-objects can
be generated, no access-plans can be calculated and no conversions
can be processed for this poor poor table.

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?

Assign the correct TABCLASS to table &SYST-MSBC1&<(>&<)>SYST-MSGV1

• What is the cause and solution for SAP error message DMC_RT_GEN116 - For table &1, no TABCLASS has been specified in DMC_MT_TABLES! ?

  The SAP error message DMC_RT_GEN116 indicates that there is an issue with the Data Migration Cockpit (DMC) where a table does not have a specified table class in the metadata table DMC_MT_TABLES. This can occur during data migration processes when the system is unable to identify how to handle a specific table due to missing configuration.
  Cause:
  The error typically arises due to one of the following reasons:
  
  Missing Configuration: The table in question is not properly configured in the DMC metadata, specifically in the DMC_MT_TABLES table, which defines the structure and properties of the tables used in the migration process.
  Incorrect Table Name: The table name specified in the migration process may not match any entry in the DMC_MT_TABLES table.
  Transport Issues: If the DMC configuration was transported from one system to another, some entries might not have been included or might have been incorrectly transported.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Check DMC_MT_TABLES:
  
  Go to transaction code SE11 (Data Dictionary) and check the table DMC_MT_TABLES.
  Look for the entry corresponding to the table name indicated in the error message (&1).
  Ensure that the TABCLASS field is populated for that entry. If it is empty, you will need to define the appropriate table class.
  
  
  
  Define Table Class:
  
  If the table class is missing, you may need to create or update the entry in DMC_MT_TABLES to include the correct TABCLASS. This typically involves specifying how the data should be handled during migration (e.g., whether it is a master data table, transactional data table, etc.).
  
  
  
  Check for Transport Issues:
  
  If the DMC configuration was recently transported, verify that all necessary objects and configurations were included in the transport request. You may need to re-transport or manually adjust the configuration.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or guides related to the Data Migration Cockpit for specific instructions on configuring tables and their classes.
  
  
  
  Testing:
  
  After making the necessary changes, test the migration process again to ensure that the error is resolved.
  
  
  
  Related Information:
