How To Fix DT366 - Field &-&: help parameter & used more than once and is import parameter

SAP Error Message - Details

• Message type: E = Error

• Message class: DT - Table activation (incl. indexes)

• Message number: 366

• Message text: Field &-&: help parameter & used more than once and is import parameter

What causes this issue?

The specified search help parameter is used more than once in the
definition of the search help attachment for the specified search
field. It is thus assigned to more than one table or structure field.
The assigned search help parameter is also the import parameter. The
table or structure field from which the input value should be copied is
therefore not clear.

System Response

The table or structure is not activated.

How to fix this error?

Assign different search help parameters to the different table or
structure fields if the search help parameter is an import parameter.

• What is the cause and solution for SAP error message DT366 - Field &-&: help parameter & used more than once and is import parameter ?

  The SAP error message DT366 indicates that a help parameter has been used more than once in a function module or method, and it is marked as an import parameter. This typically occurs in the context of using function modules or methods that involve parameter passing, particularly when dealing with selection screens or dialog programming.
  Cause:
  
  Duplicate Parameter Usage: The error arises when a parameter that is intended to be used for input (import parameter) is defined multiple times in the same context. This can happen if the same parameter is included in the function module or method signature more than once.
  Incorrect Definition: The parameter might be defined incorrectly in the function module or method, leading to confusion in how it is being utilized.
  Parameter Type: The parameter is defined as an import parameter, which means it is expected to be passed into the function/module, but it is being referenced multiple times.
  
  Solution:
  
  Check Parameter Definitions: Review the function module or method definition to ensure that each parameter is defined only once. If a parameter is needed multiple times, consider using a different approach, such as using a table or structure to pass multiple values.
  Modify the Function Module/Method: If the same parameter is required for different purposes, you may need to create additional parameters with different names or refactor the logic to avoid the need for duplicate parameters.
  Use Tables or Structures: If you need to pass multiple values, consider using a table or a structure to encapsulate the parameters instead of passing them individually.
  Check for Inherited Parameters: If the function module or method is part of a class, ensure that inherited parameters are not causing conflicts.
  
  Related Information:
  
  Function Module Documentation: Review the documentation for the specific function module or method to understand the expected parameters and their usage.
  SAP Notes: Check SAP Notes for any known issues or updates related to the specific function module or method you are working with.
  Debugging: Use the debugger to trace the execution and see where the parameters are being passed and how they are being utilized.
  
  By addressing the parameter definition and ensuring that each parameter is unique and appropriately used, you should be able to resolve the DT366 error.
