• What is the cause and solution for SAP error message /STMC/CR_MSG883 - Error while checking internal table; only one row is permitted ?

  The SAP error message /STMC/CR_MSG883 indicates that there is an issue with an internal table that is expected to contain only one row, but it contains more than one row. This error typically occurs in the context of ABAP programming, particularly when working with internal tables and database queries.
  Cause:
  The error is caused by a situation where a program or function module is trying to read data from an internal table that is expected to have a single entry, but it has multiple entries instead. This can happen due to:
  
  Incorrect Query Logic: The SQL query or selection logic may not be filtering the data correctly, leading to multiple rows being returned.
  Data Integrity Issues: The underlying data may not be as expected, resulting in multiple records being fetched when only one is anticipated.
  Improper Handling of Internal Tables: The program may not be correctly handling the internal table, such as not using the appropriate commands to ensure only one row is processed.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Query Logic: Review the SQL query or selection logic to ensure that it is correctly filtering the data. If you expect only one row, make sure to use appropriate conditions in the WHERE clause.
  
  
  Use SELECT SINGLE: If you are querying a database table and expect only one record, consider using SELECT SINGLE instead of SELECT .... This will ensure that only one record is returned.
  SELECT SINGLE * FROM your_table WHERE your_condition INTO your_structure.
  
  
  Debugging: Use the debugger to inspect the internal table before the point where the error occurs. Check how many rows are present in the internal table and why it has more than one entry.
  
  
  Handle Multiple Rows: If there is a valid scenario where multiple rows can be returned, you may need to adjust your logic to handle this case. For example, you could loop through the internal table and process each entry accordingly.
  
  
  Data Validation: Ensure that the data in the database is consistent and meets the expected criteria. If there are duplicates or unexpected entries, you may need to clean up the data.
