• What is the cause and solution for SAP error message FDT_DSM105 - Service &1 uses more than &2 decision table rows please split the service ?

  The SAP error message FDT_DSM105 indicates that a specific service in the Decision Service Management (DSM) framework is using more decision table rows than the allowed limit. This typically occurs when the number of rows in a decision table exceeds the maximum threshold set by the system, which can lead to performance issues or exceed system capabilities.
  Cause:
  
  Exceeding Row Limit: The primary cause of this error is that the decision table associated with the service has more rows than the configured limit. This limit is in place to ensure optimal performance and manageability of decision tables.
  Complex Business Logic: If the business logic is complex and requires a large number of conditions or rules, it can lead to the creation of a decision table that exceeds the row limit.
  Configuration Settings: The system may have a default configuration that limits the number of rows in decision tables, which can be adjusted based on the specific needs of the application.
  
  Solution:
  
  
  Split the Decision Table: The most straightforward solution is to split the decision table into multiple smaller tables. This can be done by:
  
  Identifying logical groupings of rules and creating separate decision tables for each group.
  Ensuring that each new decision table adheres to the row limit.
  
  
  
  Review Business Logic: Analyze the business logic to see if it can be simplified or optimized. This may involve:
  
  Reducing the number of conditions or rules.
  Combining similar rules to decrease the overall number of rows.
  
  
  
  Adjust Configuration (if applicable): If the business requirements necessitate a larger decision table, consider adjusting the configuration settings to allow for more rows. This should be done with caution and thorough testing to ensure it does not negatively impact performance.
  
  
  Consult Documentation: Refer to SAP documentation or the SAP Community for best practices on managing decision tables and services in the DSM framework.
  
  
  Testing: After making changes, thoroughly test the new configuration to ensure that the decision logic works as expected and that performance is acceptable.
