  The SAP error message CFD_REGISTRY_CHECK019, which states "Exactly one dummy field must exist in DDIC Include &1," typically arises in the context of the SAP Custom Fields and Logic (CFL) framework. This error indicates that the Data Dictionary (DDIC) include specified in the error message does not meet the requirement of having exactly one dummy field defined.
  Cause:
  The error is caused by the absence of a dummy field or the presence of more than one dummy field in the specified DDIC include. In the context of SAP, a dummy field is a placeholder field that is often used for various purposes, such as ensuring that the structure has a certain layout or for compatibility with certain functionalities.
  Solution:
  To resolve this error, you need to ensure that the specified DDIC include has exactly one dummy field defined. Here are the steps to do this:
  
  
  Access the DDIC Include: Use transaction SE11 (Data Dictionary) to access the include specified in the error message.
  
  
  Check the Fields: Review the fields defined in the include. You should look for fields that are intended to be dummy fields.
  
  
  Modify the Include:
  
  If there are no dummy fields, you need to add one. This can be a simple field of type CHAR with a length of 1 or any other appropriate type that serves as a placeholder.
  If there are multiple dummy fields, you need to remove the extra fields, leaving only one dummy field.
  
  
  
  Activate the Include: After making the necessary changes, activate the include to ensure that the changes take effect.
  
  
  Test the Changes: After activation, test the functionality that was causing the error to ensure that the issue is resolved.
  
  
  Related Information:

  Transaction Codes: Familiarize yourself with relevant transaction codes such as SE11 (Data Dictionary), SE80 (Object Navigator), and SE37 (Function Module) for further development and debugging.
