• What is the cause and solution for SAP error message DBPROC_PROXY126 - Type description does not match parameter & for proxy & ?

  The SAP error message DBPROC_PROXY126 indicates that there is a mismatch between the expected data type of a parameter and the actual data type being passed to a database procedure or function. This error typically occurs in the context of database proxy calls, where the application is trying to execute a stored procedure or function in the database, but the parameters being sent do not match the expected types defined in the database.
  Cause:
  
  Data Type Mismatch: The most common cause is that the parameter being passed to the procedure does not match the expected data type. For example, if the procedure expects an integer and a string is passed, this error will occur.
  Changes in Database Schema: If the database schema has changed (e.g., a procedure was modified to accept different types or a new version of the procedure was deployed), the application may still be using the old parameter types.
  Incorrect Mapping: If there is a mapping issue between the application and the database, such as incorrect configuration in the proxy or middleware, this can lead to type mismatches.
  
  Solution:
  
  Check Parameter Types: Review the definition of the stored procedure or function in the database and ensure that the parameters being passed from the application match the expected types.
  Update Application Code: If there are discrepancies, update the application code to ensure that the correct data types are being used when calling the procedure.
  Review Database Changes: If there have been recent changes to the database schema or stored procedures, ensure that the application is updated accordingly to reflect these changes.
  Test with Different Data: If possible, test the procedure with different data types to identify the specific parameter causing the issue.
  Check Proxy Configuration: If using a proxy or middleware, verify that the configuration is correct and that it is mapping the parameters correctly to the database procedure.
