• What is the cause and solution for SAP error message BXX106 - Function module &1 has &2 exporting parameters but only one is allowed ?

  The SAP error message BXX106 indicates that a function module is being called with an incorrect number of exporting parameters. Specifically, the error states that the function module has a certain number of exporting parameters (denoted by &2), but only one exporting parameter is allowed for that particular call.
  Cause:
  This error typically occurs when:
  
  A function module is designed to accept only one exporting parameter, but the calling program is attempting to pass multiple parameters.
  There may be a misunderstanding of the function module's interface, leading to incorrect usage.
  The function module might have been modified or incorrectly defined, leading to discrepancies in the expected number of parameters.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Function Module Definition:
  
  Go to transaction SE37 (Function Module) and enter the name of the function module that is causing the error.
  Review the parameters defined for the function module, specifically the exporting parameters. Confirm how many exporting parameters are defined.
  
  
  
  Modify the Calling Code:
  
  In the ABAP code where the function module is being called, ensure that you are only passing one exporting parameter.
  If you need to pass multiple values, consider using a structure or table as a single parameter if the function module supports it.
  
  
  
  Consult Documentation:
  
  Check the documentation for the function module to understand its intended use and the parameters it accepts. This can often be found in the function module's documentation section.
  
  
  
  Test the Changes:
  
  After making the necessary adjustments, test the program to ensure that the error is resolved and that the function module behaves as expected.
  
  
  
  Seek Help if Needed:
  
  If you are unsure about the changes or the function module's purpose, consult with a colleague or reach out to SAP support for assistance.
  
  
  
  Related Information:
  
  Function Module Interface: Understanding the interface of function modules is crucial. Each function module has a defined set of importing, exporting, changing, and tables parameters.
  ABAP Development: Familiarity with ABAP programming and function module usage is essential for troubleshooting such errors.
  SAP Notes: Check SAP Notes for any known issues or updates related to the specific function module you are working with.
