• What is the cause and solution for SAP error message DDLS390 - Function &: parameter at position & has incorrect data type & ?

  The SAP error message DDLS390 indicates that there is a problem with the data type of a parameter in a function module or method. Specifically, the error message format is as follows:
  DDLS390 Function &: parameter at position & has incorrect data type &
  Cause
  This error typically occurs when:
  
  A function module or method is called with parameters that do not match the expected data types defined in its interface.
  There may be a mismatch between the data types of the actual parameters being passed and the formal parameters defined in the function module or method.
  The data types could be incompatible, such as passing a character type where a numeric type is expected, or passing a structure that does not match the expected structure.
  
  Solution
  To resolve this error, you can take the following steps:
  
  
  Check Function Module/Method Definition:
  
  Go to the function module or method definition in the ABAP Workbench (transaction SE37 for function modules or SE80 for classes/methods).
  Review the parameter types and ensure that the data types of the parameters you are passing match the expected types.
  
  
  
  Verify Parameter Types:
  
  Ensure that the data types of the actual parameters you are passing in your call match the expected data types in the function module or method signature.
  If you are using structures, ensure that the structure fields match the expected fields in terms of both name and data type.
  
  
  
  Data Type Conversion:
  
  If necessary, perform explicit data type conversions before passing the parameters. For example, you can use CONCATENATE, CAST, or other conversion functions to ensure compatibility.
  
  
  
  Check for Changes:
  
  If the function module or method has been recently changed, ensure that the calling code has been updated accordingly to reflect any changes in parameter types.
  
  
  
  Debugging:
  
  If you are unsure where the mismatch is occurring, you can set breakpoints in your code and use the debugger to inspect the values and types of the parameters being passed.
