How To Fix LTR2_ES_CHECK263 - Data model '&1' is still in simulation mode

SAP Error Message - Details

• Message type: E = Error

• Message class: LTR2_ES_CHECK - LTR2 Checks on Embedded Specification

• Message number: 263

• Message text: Data model '&1' is still in simulation mode

What causes this issue?

During the data migration, the data must be written into the application
tables in the receiver sytem. Currently, the migration object &v1& is
still in simulation mode. This means that the data is not written into
the application table but in a simulation table instead.

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?

Go to Migration Object Settings (or use transaction
<DS:TRAN.LTS_MWBGEN_WB>LTS_MWBGEN_WB</>).
Select the migration objects still in simulation mode
Delete the migration objects (only the runtime will be deleted, all
settings are kept)
Switch off simulation mode
Recreate the migration objects
Re-execute the check to validate the current settings

• What is the cause and solution for SAP error message LTR2_ES_CHECK263 - Data model '&1' is still in simulation mode ?

  The SAP error message LTR2_ES_CHECK263 indicates that the data model you are trying to work with is still in simulation mode. This typically occurs in the context of SAP Landscape Transformation (SLT) or SAP Data Services, where data models can be created and tested in a simulation environment before being activated for production use.
  Cause:
  The primary cause of this error is that the data model (indicated by &1 in the error message) has not been fully activated or is still in a testing phase. In simulation mode, certain operations may be restricted, and the model cannot be used for actual data replication or transformation processes.
  Solution:
  To resolve this error, you need to activate the data model. Here are the steps you can follow:
  
  
  Access the Data Model: Go to the relevant transaction or application where the data model is defined (e.g., SLT configuration or Data Services).
  
  
  Check the Status: Verify the current status of the data model. It should indicate that it is in simulation mode.
  
  
  Activate the Data Model:
  
  Look for an option to activate or publish the data model. This may be labeled as "Activate," "Publish," or similar.
  Follow the prompts to complete the activation process.
  
  
  
  Review Dependencies: Ensure that all dependencies and prerequisites for activation are met. This may include checking for any required configurations or settings that need to be in place.
  
  
  Test the Activation: After activation, perform a test to ensure that the data model is functioning as expected and that the error no longer appears.
  
  
  Related Information:
  
  Documentation: Refer to the official SAP documentation for SLT or Data Services for detailed instructions on managing data models and understanding their lifecycle.
  Transaction Codes: Familiarize yourself with relevant transaction codes (e.g., LTRC for SLT configuration) that can help you navigate the system more effectively.
  Support: If you continue to experience issues, consider reaching out to SAP support or consulting with your internal SAP team for further assistance.
  
  By following these steps, you should be able to resolve the error and successfully activate your data model for use in production.
