• What is the cause and solution for SAP error message /ECRS/BL_MD007 - SAVE method in create mode without calling CHANGE first ?

  The SAP error message /ECRS/BL_MD007 typically occurs in the context of the SAP ECRS (Enterprise Central Component for Retail Solutions) module when trying to save a business logic model (BL) without first calling the CHANGE method. This error indicates that the system expects a change operation to be initiated before saving the data.
  Cause:
  The error arises because the system requires a specific sequence of method calls when working with business logic models. In this case, the SAVE method cannot be executed directly in create mode without first invoking the CHANGE method. The CHANGE method is necessary to indicate that the model is being modified or created, and it prepares the system to handle the subsequent save operation.
  Solution:
  To resolve this error, you should ensure that the following sequence of method calls is followed:
  
  
  Call the CHANGE Method: Before attempting to save the model, you need to call the CHANGE method. This indicates that you are making changes to the model.
  
  
  Perform the Necessary Changes: After calling the CHANGE method, make any necessary modifications to the model data.
  
  
  Call the SAVE Method: Once the changes have been made, you can then call the SAVE method to persist the changes to the database.
  
  
  Example Sequence:
  CALL METHOD /ECRS/BL_MD->CHANGE
    EXPORTING
      ...  " parameters for change
    EXCEPTIONS
      ...  " handle exceptions
  
  " Make changes to the model here
  
  CALL METHOD /ECRS/BL_MD->SAVE
    EXPORTING
      ...  " parameters for save
    EXCEPTIONS
      ...  " handle exceptions
  Related Information:
  
  Documentation: Refer to the SAP ECRS documentation for detailed information on the business logic model and the required method calls.
  Debugging: If you continue to encounter issues, consider using the SAP debugger to trace the method calls and ensure that the CHANGE method is being called before SAVE.
  SAP Notes: Check for any relevant SAP Notes that may address this error or provide additional context or fixes.
  
  By following the correct sequence of method calls, you should be able to resolve the error and successfully save your business logic model.
