  Cause:
  This error usually arises when the program or function module expects a single variant or a table of variants, but instead receives an incorrect data type or structure. Common causes include:
  
  Incorrect Data Type: The program might be receiving a data type that is not compatible with what it expects (e.g., a string instead of a variant).
  Empty or Null Values: If the variant is not properly defined or is empty, the system may throw this error.

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Input Parameters: Ensure that the parameters being passed to the function or method are of the correct type. If a single variant is expected, make sure you are passing a single variant object. If a table of variants is expected, ensure you are passing a properly defined internal table of variants.
  
  
  Define Variants Properly: If you are using variants, make sure they are defined correctly in the system. You can check the variants in transaction codes like SE38 (for reports) or SE93 (for transaction variants).
  
  
  Debugging: If you have access to the ABAP code, you can debug the program to see what values are being passed to the function/module. This can help identify if the wrong data type is being sent.
  
  
  Consult Documentation: Review the documentation for the specific function module or method you are using to ensure you are using it correctly.
