• What is the cause and solution for SAP error message W7055 - Error occurred during compulsory parameter transfer ?

  SAP Error Message:
  
  W7055 - Error occurred during compulsory parameter transfer
  
  Cause:
  The error message W7055 typically occurs when a required (compulsory) parameter that needs to be passed between SAP programs, function modules, or screens is missing or not correctly transferred. This can happen in scenarios such as:
  
  Calling a transaction or program that expects certain input parameters, but these parameters are not provided.
  Navigation between screens or modules where mandatory parameters are not passed via the parameter interface.
  Custom developments or enhancements where parameter passing is incorrectly handled.
  Issues in batch input sessions or variants where compulsory parameters are not set.
  
  In short, the system expects certain parameters to be transferred for the process to continue, but these parameters are missing or invalid.
  
  Solution:
  To resolve the W7055 error, follow these steps:
  
  
  Identify the Missing Parameter:
  
  Check the short dump or error log to find which parameter is missing.
  Review the program or transaction code where the error occurs.
  Use debugging to trace the parameter passing between programs or screens.
  
  
  
  Ensure Proper Parameter Passing:
  
  If calling a transaction or program, make sure all required parameters are passed correctly.
  For custom developments, verify that the parameter interface (IMPORTING, EXPORTING, CHANGING parameters) is correctly defined and used.
  In screen navigation (module pool programming), ensure that the parameters are passed via CALL SCREEN or SET PARAMETER ID statements.
  
  
  
  Check Variants and Batch Input:
  
  If the error occurs during batch input or when using variants, verify that all mandatory fields are filled in the variant.
  Adjust the variant or batch input session to include the compulsory parameters.
  
  
  
  Review SAP Notes and Documentation:
  
  Search for SAP Notes related to the specific transaction or program.
  Sometimes, SAP provides patches or corrections for known issues causing this error.
  
  
  
  Testing:
  
  After corrections, test the transaction or program to ensure the error no longer occurs.
  Use debugging to confirm that all compulsory parameters are correctly transferred.

  Parameter Passing in SAP:
  
  SAP programs often require parameters to be passed explicitly to ensure data consistency and correct processing. Missing parameters can cause runtime errors or unexpected behavior.
  
  
  Common Scenarios:
  
  Calling transaction variants without required parameters.
  Custom reports or function modules expecting input parameters.
  Screen sequences in module pool programming.
  
  
  
  Debugging Tips:
  
  Use transaction SE38 or SE80 to locate the program.
  Set breakpoints at the start of the program or at parameter import statements.
  Check the values of parameters during runtime.
  
  
  
  SAP Notes and Support:
  
  Check SAP Support Portal for notes related to message W7055.
  Sometimes, the error is linked to specific SAP modules or versions.
  
  
  
  
  Summary:
  W7055 error occurs due to missing compulsory parameters during parameter transfer between SAP programs or screens. The solution involves identifying the missing parameter, ensuring correct parameter passing, verifying variants or batch inputs, and testing the corrected process.
