• What is the cause and solution for SAP error message FDT_DSM106 - Service &1 uses more than &2 tree nodes, please split the service ?

  The SAP error message FDT_DSM106 indicates that a service in the SAP system is using more tree nodes than the allowed limit. This typically occurs in the context of the SAP Fiori Design Time (FDT) or when working with the SAP Business Rules Framework (BRF+). The error suggests that the service is too complex or has too many elements, which can lead to performance issues or exceed system limitations.
  Cause:
  
  Complex Service Definition: The service may have a complex structure with too many nodes, which can happen if there are many conditions, actions, or rules defined within the service.
  System Limitations: SAP has predefined limits on the number of nodes that can be used in a service to ensure optimal performance and manageability.
  Inefficient Design: The design of the service may not be optimal, leading to an excessive number of nodes being utilized.
  
  Solution:
  
  
  Split the Service: The primary solution is to split the service into multiple smaller services. This can be done by:
  
  Identifying logical groupings of rules or conditions and creating separate services for each group.
  Reducing the complexity of the service by breaking down large rules into smaller, more manageable ones.
  
  
  
  Optimize the Service: Review the service for any unnecessary nodes or redundancies. Simplifying the logic can help reduce the number of nodes.
  
  Remove any unused or redundant conditions and actions.
  Combine similar rules where possible to minimize the number of nodes.
  
  
  
  Review Documentation: Check the SAP documentation for any specific guidelines or best practices regarding service design and node limits.
