How To Fix E2355 - Parameter assignment cannot be fully specified

SAP Error Message - Details

• Message type: E = Error

• Message class: E2 - DE Data Dictionary

• Message number: 355

• Message text: Parameter assignment cannot be fully specified

What causes this issue?

You wanted to <DS:TX.DDDOK_SHLP_TBSH>link</> a search help to a
structure field or a table. To determine how the values are passed
between the input mask and the search help, the
<DS:TX.DDDOK_SHLP_PARAMETER>interface parameters</> of the search help
must be assigned to the fields of the structure or the key fields of
the table.
The system tries to generate a proposed assignment based on parameters
that share the same domain. In this case, the system was unable to find
a suitable field for all of the interface parameters of the search
help.

System Response

The assignment remains generic for those interface parameters for which
no appropriate field could be found.

How to fix this error?

Check the assignment. You may need to assign a field from another
structure or a constant to one of the unassigned parameters.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message E2355 - Parameter assignment cannot be fully specified ?

  The SAP error message E2355, "Parameter assignment cannot be fully specified," typically occurs in the context of ABAP programming, particularly when dealing with function modules, methods, or subroutines. This error indicates that there is an issue with how parameters are being passed to a function or method, specifically that the parameters cannot be fully resolved or assigned.
  Causes:
  
  
  Incomplete Parameter Specification: The parameters being passed to a function or method are not fully specified. This can happen if:
  
  Some parameters are missing.
  Parameters are incorrectly defined or mismatched in terms of data types.
  Optional parameters are not being handled correctly.
  
  
  
  Ambiguous Parameter Assignment: If there are multiple parameters with the same name or if the parameter list is not clear, the system may not be able to determine which parameter is being referenced.
  
  
  Incorrect Use of Structures or Tables: If you are passing a structure or an internal table, and the fields do not match the expected parameters in the function module or method, this can lead to this error.
  
  
  Solutions:
  
  
  Check Parameter Definitions: Review the function module or method definition to ensure that all required parameters are being passed correctly. Make sure that the data types and names match.
  
  
  Use Named Parameter Assignment: When calling a function or method, use named parameter assignment to clarify which parameters are being assigned values. This can help avoid ambiguity.
  CALL FUNCTION 'FUNCTION_NAME'
    EXPORTING
      param1 = value1
      param2 = value2.
  
  
  Review Optional Parameters: If the function or method has optional parameters, ensure that they are being handled correctly. If you are not passing an optional parameter, make sure that the function can handle it without issues.
  
  
  Debugging: Use the ABAP debugger to step through the code and check the values being passed to the function or method. This can help identify any discrepancies.
  
  
  Check for Overloading: If there are overloaded methods or functions, ensure that the correct version is being called with the appropriate parameters.
  
  
  Related Information:
  
  Documentation: Refer to the SAP documentation for the specific function module or method you are working with to understand the expected parameters and their types.
  SAP Notes: Check SAP Notes for any known issues or updates related to the specific function or method you are using.
  Community Forums: Consider searching or posting on SAP community forums or platforms like SAP Community, Stack Overflow, or other ABAP-related forums for additional insights and solutions from other developers.
  
  By following these steps, you should be able to identify and resolve the cause of the E2355 error in your SAP ABAP code.
