• What is the cause and solution for SAP error message EZ755 - Import parameter &1 has DDIC type &2 instead of &3 ?

  The SAP error message EZ755 indicates that there is a mismatch between the expected data dictionary (DDIC) type of an import parameter and the actual type that is being passed to it. This typically occurs in the context of function modules, methods, or other callable objects where parameters are defined with specific data types.
  Cause:
  The error occurs when:
  
  An import parameter is defined with a specific DDIC type (e.g., a structure, table, or simple data type).
  The actual value being passed to this parameter does not match the expected DDIC type. For example, if the parameter is defined as a structure but a simple data type is being passed, or vice versa.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Function Module/Method Definition:
  
  Go to the function module or method where the error is occurring.
  Check the definition of the import parameters and their expected DDIC types.
  
  
  
  Verify the Calling Code:
  
  Look at the code that is calling the function module or method.
  Ensure that the data being passed to the import parameter matches the expected DDIC type. This may involve:
  
  Changing the data type of the variable being passed.
  Creating a new variable of the correct type and assigning the value to it before passing it.
  
  
  
  
  
  Data Conversion:
  
  If necessary, perform any required data conversions to ensure that the data being passed matches the expected type. This could involve using conversion functions or methods.
  
  
  
  Testing:
  
  After making the necessary changes, test the function/module again to ensure that the error is resolved.
  
  
  
  Related Information:
  
  Data Dictionary (DDIC): The DDIC in SAP is a central repository that defines the structure of data used in the system. It includes definitions for tables, views, data elements, domains, and more.
  Function Modules and Methods: These are reusable pieces of code in SAP that can be called from various programs. They have defined interfaces that specify the parameters that can be passed to them.
  Debugging: If you are unable to identify the issue, consider using the debugger to step through the code and inspect the values being passed to the function/module.
  
  By following these steps, you should be able to identify and correct the cause of the EZ755 error in your SAP environment.
