• What is the cause and solution for SAP error message TG455 - Table & has more than 749 fields; conversion not possible in all DBMSs ?

  The SAP error message TG455 indicates that a specific database table has more than 749 fields, which can lead to issues with data conversion in certain Database Management Systems (DBMS). This limitation arises because some DBMSs have restrictions on the number of fields that can be handled in a single table, particularly when it comes to data conversion or migration processes.
  
  Cause:
  
  Exceeding Field Limit: The primary cause of this error is that the table in question has more than 749 fields. This can happen due to the design of the table, where multiple attributes or characteristics are stored in a single table.
  Database Compatibility: Different DBMSs have varying limitations on the number of fields per table. Some may not support tables with a high number of fields, leading to conversion issues.
  
  
  Solution:
  
  
  Table Redesign: Consider redesigning the table to reduce the number of fields. This can involve:
  
  Normalization: Breaking the table into multiple related tables
