• What is the cause and solution for SAP error message FDT_DSM104 - Service &1 uses more than &2 rules, please split the service ?

  The SAP error message FDT_DSM104 indicates that a service in the SAP system is using more rules than the allowed limit. This typically occurs in the context of the SAP Fiori Data Management (FDT) framework, where services are defined to handle specific business logic and data processing.
  Cause:
  The error arises when a service exceeds the maximum number of rules that can be processed in a single service definition. This limit is set to ensure optimal performance and maintainability of the service. When the number of rules exceeds the threshold, the system cannot process the service as intended, leading to this error message.
  Solution:
  To resolve this error, you need to split the service into multiple services, each containing a manageable number of rules. Here are the steps you can follow:
  
  
  Analyze the Service: Review the service that is causing the error to understand how many rules it contains and what those rules are doing.
  
  
  Identify Logical Groupings: Determine if the rules can be logically grouped into separate services. For example, if the rules pertain to different business processes or data types, consider creating distinct services for each group.
  
  
  Create New Services: Create new service definitions in the FDT framework for the identified groups of rules. Ensure that each new service adheres to the rule limit.
  
  
  Update References: If the original service is being called from other parts of the application, update those references to point to the new services as necessary.
  
  
  Test the New Services: After splitting the services, thoroughly test each new service to ensure that they function correctly and that the business logic is preserved.
  
  
  Documentation: Document the changes made to the services for future reference and maintenance.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes or documentation that may provide additional insights or updates regarding this error message.

  By following these steps, you should be able to resolve the FDT_DSM104 error and ensure that your services are functioning correctly within the defined limits.
