Getting error in script component for Input0Buffer and Output0Buffer while splitting one multivalue columns to multiple rows used as transformation component

Question

Hi ppl,

I am getting error while using Input0Buffer and Output0Buffer in script component. csv file is the source, script component is the transformation, DB is the output destination. Kindly help on the below error.

Input0Buffer.Identifier - Ambiguity between Input0Buffer.Identifier and Input0Buffer.Identifier
Output0Buffer.Identifier - 'object' does not contain definition for 'Identifier'

The below the piece of code.

public class ScriptMain : UserComponent
{
public object Output0Buffer { get; private set; }

 * Example of using a File connection manager to acquire a file path:
 *  object rawConnection = Connections.Prices_zip.AcquireConnection(transaction);
 *  string filePath = (string)rawConnection;
 *
 * Example of releasing a connection manager:
 *  Connections.SalesDB.ReleaseConnection(rawConnection);

Answer 1

Got it working!

1. Changed SynchronousInputID as None option for removing the Output0Buffer related error.
2. Ambiguous names error. Changed the input and output columns as different.

Thanks for the responses everyone!

Answer 2

Hi @Pavithra Subramanian ,

1.Please check if you add new column in Output Columns.

2.Please refer to the script in Lesson 4-3: Add error flow redirection:
public override void Input0_ProcessInputRow(Input0Buffer Row)
{
Row.ErrorDescription = this.ComponentMetaData.GetErrorDescription(Row.ErrorCode);
}
Note: ErrorDescription is output column and ErrorCode is input column.

Best Regards,
Mona
