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?

Check why there are no active header tables in the data model (perhaps
the header tables are set inactive because they do not exist or are

embedded specification.

• What is the cause and solution for SAP error message LTR2_ES_CHECK198 - Data model '&1' active, but no active header table exists ?

  The SAP error message LTR2_ES_CHECK198 indicates that a data model is active, but there is no corresponding active header table associated with it. This can occur in the context of SAP's data modeling tools, particularly when working with data models in SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  
  Missing Header Table: The primary cause of this error is that the header table that should be linked to the data model is either not created, not activated, or has been deleted.
  Inconsistent Data Model: The data model may have been modified or not properly configured, leading to inconsistencies between the model and its associated tables.
  Transport Issues: If the data model was transported from one system to another, there may have been issues during the transport process that resulted in missing objects.

  Check Header Table: Verify if the header table associated with the data model exists and is active. You can do this by:
  
  Navigating to the relevant data model in the SAP GUI.
  Checking the associated tables in the data model configuration.
  
  
  
  Activate Header Table: If the header table exists but is not active, activate it. You can do this through the Data Dictionary (SE11) or the relevant transaction for activating objects.
  
  
  Recreate Header Table: If the header table does not exist, you may need to recreate it. This can involve:
  
  Creating a new header table that matches the specifications required by the data model.
  Ensuring that all necessary fields and keys are defined correctly.
  
  
  
  Check Transport Logs: If the issue arose after a transport, check the transport logs for any errors or warnings that might indicate what went wrong during the transport process.
  
  
  Consult Documentation: Review the SAP documentation for the specific data model you are working with to ensure that all prerequisites and configurations are met.
