• What is the cause and solution for SAP error message ESH_OM_PC019 - Model ID must not be in customer name space ?

  The SAP error message ESH_OM_PC019 indicates that a model ID you are trying to use is in a customer namespace, which is not allowed for certain operations in the SAP system. This typically occurs in the context of SAP Enterprise Search or SAP HANA, where specific naming conventions and restrictions apply to model IDs.
  Cause:
  The error arises when:
  
  You are attempting to create or modify a model ID that falls within a customer namespace (usually starting with a specific prefix that indicates it is a custom development).
  The system restricts the use of certain namespaces for specific operations to maintain integrity and avoid conflicts with standard SAP objects.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Model ID: Verify the model ID you are trying to use. Ensure that it does not start with a customer-specific prefix (like Z or Y). If it does, you will need to choose a different model ID that is not in the customer namespace.
  
  
  Use Standard Model IDs: If you are creating a new model, use a standard model ID provided by SAP that does not fall under the customer namespace.
  
  
  Modify Existing Models: If you are trying to modify an existing model that is in the customer namespace, consider creating a new model with a valid ID and replicating the necessary configurations.
  
  
  Consult Documentation: Refer to the SAP documentation for guidelines on naming conventions and the use of model IDs in your specific version of SAP.
  
  
  Contact SAP Support: If you are unsure about the naming conventions or if the issue persists, consider reaching out to SAP support for assistance.
