• What is the cause and solution for SAP error message SADL_ENTITY010 - Combination of parameter derviation and default value is not allowed ?

  The SAP error message SADL_ENTITY010 indicates that there is an issue with the combination of parameter derivation and default values in the context of SAP's Service Data Layer (SADL). This error typically arises when you are trying to define a parameter in a way that is not allowed by the system's rules for parameter handling.
  Cause:
  The error occurs when:
  
  You have defined a parameter in a SADL entity that has both a default value and a derivation rule.
  The system does not allow a parameter to have both a default value and a derivation because it creates ambiguity in how the parameter should be populated.
  
  Solution:
  To resolve the SADL_ENTITY010 error, you can take the following steps:
  
  
  Review Parameter Definitions:
  
  Check the parameters defined in your SADL entity. Look for any parameters that have both a default value and a derivation rule.
  
  
  
  Remove Conflicting Definitions:
  
  Decide whether you want to use a default value or a derivation for the parameter. Remove one of them based on your business logic:
  
  If you want to use a default value, remove the derivation rule.
  If you want to use a derivation, remove the default value.
  
  
  
  
  
  Test Changes:
  
  After making the necessary changes, test the entity to ensure that the error no longer occurs and that the functionality works as expected.
  
  
  
  Documentation and Best Practices:
  
  Refer to SAP documentation for best practices on defining parameters in SADL entities. This can help you avoid similar issues in the future.
