How To Fix DH189 - Parameter & is no longer the first EXPORT parameter

SAP Error Message - Details

• Message type: E = Error

• Message class: DH - DD: Messages for search helps

• Message number: 189

• Message text: Parameter & is no longer the first EXPORT parameter

What causes this issue?

In the active version of the search help, parameter &V1& is the first
EXPORT parameter. This was changed in the version to be activated. When
you use the search help with a direct <DS:TX.DDDOK_SHLP_TBSH>attachnent
</> to a screen field (and when you assign to parameters or selection
options with the MATCHCODE-OBJECT addition), the first EXPORT parameter
of the search help is always connected with the search field. This
change therefore can result in unwanted side-effects in such
attachments.

System Response

The action is continued with a warning message.

How to fix this error?

Check if the search help is used in the specified form. If this is the
case, or if the check is too time-consuming), it might be desirable to
change the order of the EXPORT parameters back to the old order.
In general, however, you should avoid directly attaching search helps
to screen fields. Use the options for attaching search helps in the
ABAP Dictionary.

Procedure for System Administrators

• What is the cause and solution for SAP error message DH189 - Parameter & is no longer the first EXPORT parameter ?

  The SAP error message DH189, which states "Parameter & is no longer the first EXPORT parameter," typically occurs in ABAP programs when there is an issue with the way parameters are defined or called in a function module or method. This error indicates that the specified parameter is expected to be the first EXPORT parameter, but it is not.
  Cause:
  
  Parameter Order: In SAP function modules, the first parameter in the EXPORT section is expected to be the primary output parameter. If the order of parameters is changed or if the function module is called incorrectly, this error can occur.
  Changes in Function Module: If the function module has been modified (e.g., the order of parameters has changed), and the calling program has not been updated accordingly, this error can arise.
  Inconsistent Interface: If the interface of the function module has been changed in a way that affects the EXPORT parameters, and the calling program still uses the old interface.
  
  Solution:
  
  Check Function Module Definition: Review the definition of the function module or method to ensure that the parameters are defined correctly and that the first EXPORT parameter is as expected.
  Update Calling Program: If the function module has been modified, update the calling program to match the new parameter order. Ensure that the first EXPORT parameter is correctly referenced.
  Recompile: After making changes, recompile the affected programs to ensure that the changes take effect.
  Check for Enhancements: If the function module is part of a standard SAP delivery, check if there are any enhancements or modifications that might have affected the parameter order.
  Consult Documentation: If available, refer to the documentation for the function module to understand the expected parameter order and usage.
  
  Related Information:
  
  Function Module Interface: You can view the interface of the function module in transaction SE37 (Function Builder) or SE80 (Object Navigator).
  ABAP Debugger: Use the ABAP debugger to step through the code and identify where the error occurs.
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that might address this specific error or provide additional context.
  Code Review: Conduct a code review to ensure that all function calls are consistent with the defined interfaces.
  
  By following these steps, you should be able to resolve the DH189 error and ensure that your ABAP programs function correctly.
