  Cause:
  The error message SOI173 typically arises due to one or more of the following reasons:

  Database-Specific Limitations: Certain data types in SAP may not be supported by the underlying database system (e.g., Oracle, SQL Server, etc.). For example, a field defined as a certain type in SAP may not have a direct equivalent in the database.
  
  
  Field Length Issues: The length of the field in the DDIC may exceed the maximum length allowed by the database type.
  
  
  Incorrect Configuration: There may be configuration issues in the database connection or the way the data model is set up.
