• What is the cause and solution for SAP error message MDC_MODEL100 - Names of model table &1 and active table &2 of BO &3 are not identical ?

  The SAP error message MDC_MODEL100 indicates that there is a mismatch between the names of the model table and the active table for a Business Object (BO) in the context of SAP's Model Driven Architecture (MDA) or similar frameworks. This error typically arises when there is an inconsistency in the configuration or setup of the data model.

  Solution:
  
  Check Naming Conventions: Verify that the names of the model table and the active table are indeed supposed to be identical. If they are not, you may need to correct the configuration.
  Update the Model: If the model table name is correct, you may need to update the active table to match the model table name. This can often be done through the relevant transaction codes or tools in SAP.
  Recreate the Active Table: If the active table is corrupted or incorrectly named, you may need to drop and recreate it based on the model table definition.
  Transport Consistency: Ensure that all transports related to the Business Object have been correctly applied and that there are no missing objects.
