• What is the cause and solution for SAP error message /SAPDMC/LSMW526 - The wildcard value for & - & - & is not unique ?

  The SAP error message /SAPDMC/LSMW526 indicates that there is an issue with the use of wildcard values in the context of the Legacy System Migration Workbench (LSMW). This error typically arises when the system encounters multiple entries that match the wildcard criteria, leading to ambiguity in the data selection process.
  Cause:
  The error occurs when:
  
  You are using a wildcard character (like * or ?) in a selection criterion.
  The wildcard matches multiple records in the database, making it unclear which specific record should be selected.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Refine the Wildcard Criteria: 
  
  Modify the selection criteria to be more specific. Instead of using a broad wildcard, try to narrow down the search parameters to ensure that only one unique record matches the criteria.
  
  
  
  Check Data Consistency:
  
  Review the data in the relevant tables to identify why multiple records are being returned. You may need to clean up or consolidate data to ensure uniqueness.
  
  
  
  Use Exact Values:
  
  If possible, replace the wildcard with exact values that you know will uniquely identify the record you want to work with.
  
  
  
  Review LSMW Settings:
  
  Check the settings and mapping in your LSMW project to ensure that the fields and values are correctly defined and that there are no unintended wildcards being used.
  
  
  
  Test with Different Values:
  
  If you are unsure which values are causing the issue, try testing with different combinations of values to see if you can isolate the problem.
