• What is the cause and solution for SAP error message CME_DTYPE054 - Only & levels are possible ?

  The SAP error message CME_DTYPE054 with the description "Only & levels are possible" typically occurs in the context of data type definitions or when working with hierarchical data structures in SAP. This error indicates that the system is expecting a certain level of hierarchy or data structure, but the input provided does not meet the expected criteria.
  Cause:
  
  Incorrect Level Specification: The error often arises when a user tries to define or manipulate a hierarchy with more levels than allowed. For example, if the system is configured to only allow a maximum of 3 levels, and the user attempts to create a structure with 4 levels, this error will be triggered.
  Data Type Restrictions: The data type being used may have inherent restrictions on the number of levels that can be defined.
  Configuration Issues: There may be configuration settings in the SAP system that limit the number of levels for certain data types or structures.
  
  Solution:
  
  Check Hierarchy Levels: Review the hierarchy or data structure you are trying to create or modify. Ensure that the number of levels does not exceed the allowed limit as defined in the system.
  Adjust Data Structure: If you need to work with more levels, consider restructuring your data or hierarchy to fit within the allowed limits.
  Consult Documentation: Refer to SAP documentation or help resources for the specific module you are working with to understand the limitations and configurations related to data types and hierarchies.
  System Configuration: If you believe that the limit is too restrictive for your business needs, consult with your SAP Basis or configuration team to see if adjustments can be made to the system settings.
  Error Logs: Check the system logs for any additional error messages or warnings that may provide more context about the issue.
