• What is the cause and solution for SAP error message /IWFND/CM_MGW104 - You are in read-only mode ?

  The SAP error message /IWFND/CM_MGW104 You are in read-only mode typically occurs in the context of SAP Gateway services, particularly when trying to perform operations that require write access (like POST, PUT, or DELETE) but the system is configured to allow only read operations.
  Cause:
  
  System Configuration: The system may be set to read-only mode due to configuration settings. This can happen in various scenarios, such as during maintenance, upgrades, or specific system settings that restrict write access.
  User Authorization: The user executing the operation may not have the necessary authorizations to perform write operations on the service.
  Service Configuration: The OData service might be configured to allow only read operations. This can be due to the service definition or the underlying data model.
  Transaction Locking: The system might be in a state where transactions are locked, preventing any write operations.
  
  Solution:
  
  Check System Configuration: Verify if the system is intentionally set to read-only mode. This can be checked in the system settings or by consulting with your system administrator.
  User Authorizations: Ensure that the user has the necessary authorizations to perform write operations. This can be done by checking the user's roles and authorizations in the SAP system.
  Service Configuration: Review the OData service configuration in the SAP Gateway. Ensure that the service is designed to allow write operations. You can check this in the Service Builder (transaction code SEGW).
  Check for Locks: Investigate if there are any locks on the database or transactions that might be preventing write operations. You can use transaction codes like SM12 to check for locks.
  Testing in Different Environments: If you are working in a development or test environment, try to replicate the issue in a different environment to see if it is environment-specific.
