• What is the cause and solution for SAP error message WS055 - Conversion different to known one ( & & <-> & & ) ?

  SAP Error Message:
  WS055 Conversion different to known one ( & & <-> & & )
  
  Meaning / Cause:
  This error occurs during the conversion of data between internal and external formats in SAP. Specifically, it indicates that the conversion routine being used for a particular data element or field is different from the one previously known or expected by the system.
  
  SAP uses conversion routines to transform data between internal (system) format and external (user) format.
  When a conversion routine is changed or inconsistent (e.g., due to customizing changes, transport inconsistencies, or program changes), SAP detects a mismatch.
  The message WS055 is triggered when the system finds that the conversion routine currently assigned to a data element or domain differs from the one it has stored or expects.
  
  
  Typical Scenarios:
  
  Changing the conversion routine for a domain or data element after data has already been stored or processed.
  Transporting objects between systems where conversion routines differ.
  Inconsistent customizing or program logic related to conversion routines.
  Using a conversion routine that conflicts with the one SAP expects for a particular field.
  
  
  Solution / How to Fix:
  
  
  Check Conversion Routine Assignment:
  
  Go to transaction SE11 (Data Dictionary).
  Look up the domain or data element related to the field causing the error.
  Check the assigned conversion routine (field "Conversion Routine" in domain or data element).
  Verify if the conversion routine has been changed recently.
  
  
  
  Consistency Check:
  
  Run consistency checks on the domain/data element.
  Use transaction SE14 or SE16 to check data consistency if applicable.
  
  
  
  Revert or Align Conversion Routines:
  
  If the conversion routine was changed unintentionally, revert it to the original one.
  If a new conversion routine is required, ensure all related data and programs are adjusted accordingly.
  
  
  
  Transport and System Consistency:
  
  Check if transports have been imported correctly.
  Ensure that the conversion routine is consistent across all systems (DEV, QAS, PRD).
  
  
  
  Debugging:
  
  If the error occurs during runtime, debug the program to see which field and conversion routine are involved.
  Check the internal and external values being converted.
  
  
  
  SAP Notes and Support:
  
  Search for SAP Notes related to WS055 for any known bugs or patches.
  If the problem persists, consider raising a support ticket with SAP including detailed information about the field, domain, and conversion routines.
  
  
  
  
  Related Information:
  
  
  Conversion Routines in SAP:
  
  Conversion routines are used to convert data between internal SAP format and external user format. Examples include date conversions, unit conversions, or custom routines.
  
  
  Where Conversion Routines are Defined:  
  
  Domains (SE11) have a field for conversion routines.
  Data elements can also have conversion routines.
  Conversion routines are implemented as function modules or routines with specific naming conventions (e.g., CONVERSIONEXIT*).
  
  
  
  Common Conversion Routines:  
  
  ALPHA for leading zeros  
  DATE for date formatting  
  UNIT for unit conversions
