• What is the cause and solution for SAP error message DDLS522 - Input parameters & could not be mapped onto database types ?

  The SAP error message DDLS522 indicates that there is an issue with the mapping of input parameters to database types in a Data Definition Language (DDL) statement. This typically occurs when there is a mismatch between the data types defined in the ABAP program or the DDL statement and the corresponding database types in the underlying database.
  Causes:
  
  
  Data Type Mismatch: The input parameters defined in the ABAP program do not match the expected data types in the database schema. For example, if an ABAP parameter is defined as a string but the database expects an integer, this error can occur.
  
  
  Unsupported Data Types: The data types used in the ABAP program may not be supported by the underlying database. For instance, certain complex types or structures may not have a direct mapping in the database.
  
  
  Incorrect Length or Precision: If the length or precision of a data type in ABAP does not match the definition in the database, it can lead to this error.
  
  
  Database-Specific Constraints: Some databases have specific constraints or requirements for data types that may not be met by the ABAP definitions.
  
  
  Solutions:
  
  
  Check Data Type Definitions: Review the data type definitions in both the ABAP program and the database schema. Ensure that they match in terms of type, length, and precision.
  
  
  Adjust ABAP Parameters: Modify the ABAP parameters to ensure they are compatible with the database types. This may involve changing the data type or adjusting the length/precision.
  
  
  Use Compatible Types: If you are using complex types or structures, consider using simpler types that have a direct mapping to the database.
  
  
  Database Documentation: Refer to the documentation of the specific database you are using to understand the supported data types and their mappings.
  
  
  Testing: After making changes, test the DDL statement again to ensure that the error is resolved.
