  The SAP error message /SAPAPO/CA_EMH_UI006 with the description "Type of reaction has to be defined unique" typically occurs in the context of SAP Advanced Planning and Optimization (APO), particularly when dealing with the configuration of reaction types in the system.
  Cause:
  This error usually arises when there is an attempt to define a reaction type that is not unique within the system. In SAP APO, reaction types are used to define how the system should respond to certain conditions or events in the planning process. If there are multiple entries for the same reaction type, the system cannot determine which one to use, leading to this error.
  Solution:
  To resolve this error, you should follow these steps:
  
  
  Check Existing Reaction Types:
  
  Navigate to the configuration settings for reaction types in SAP APO.
  Look for the existing reaction types defined in the system and check for duplicates.
  
  
  
  Ensure Uniqueness:
  
  If you find duplicate entries, you will need to either delete or modify them to ensure that each reaction type is unique.
  Make sure that the naming conventions used for reaction types are distinct and do not overlap.
  
  
  
  Review Configuration:
  
  Go through the configuration settings related to the specific planning area or process where the error occurred.
  Ensure that all necessary settings are correctly defined and that there are no conflicting entries.
  
  
  
  Testing:
  
  After making the necessary changes, test the configuration to ensure that the error no longer occurs.
  Run the planning process again to verify that the system behaves as expected.
