• What is the cause and solution for SAP error message FDT_CORE804 - Message text of &1(&2) does not have a second message variable ?

  The SAP error message FDT_CORE804 indicates that there is an issue with a message text that is expected to have a second message variable, but it does not. This typically occurs in the context of SAP's Flexible Data Import (FDI) or Flexible Data Transfer (FDT) framework, where messages are defined with placeholders for dynamic content.
  Cause:
  The error is caused by a mismatch between the message definition and the actual message text being used. Specifically, the message text is defined to expect two variables (placeholders), but only one variable is provided when the message is triggered. This can happen due to:
  
  Incorrect Message Definition: The message might be defined in the system with two placeholders, but the actual message text does not include a second variable.
  Coding Error: The code that triggers the message might be incorrectly passing only one variable instead of two.
  Configuration Issues: There may be issues in the configuration of the message handling in the FDT framework.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Message Definition:

  Review Code:
  
  If you have access to the ABAP code that triggers this message, check to ensure that it is passing the correct number of variables. If the message expects two variables, make sure both are being provided.
  
  
  
  Adjust Message Handling:
  
  If the message is being triggered from a configuration or a custom program, ensure that the message handling logic is correctly implemented to match the message definition.
  
  
  
  Consult Documentation:
