  Hi guys,

  It would be nice if you could help me with the following issue:

  I need to read a DFT level variable in a script component (set as transformation). Depending on its value make some calculation and then update its value again. That's should be made for every incomming row. The problem that I´ve encountered is I tried to read the variable in the row processing method and write it in the postexecute() method. I got this error "The collection of variables locked for read and write access is not available outside of PostExecute." But I really need the value of the variable in the main method.

  Below is my code

  public override void PostExecute()

  {

  base.PostExecute();

  /*

  Add your code here for postprocessing or remove if not needed

  You can set read/write variables here, for example:

  Variables.MyIntVar = 100

  */

  Variables.receiptKey = newReceipt;

  }

  public override void Input0_ProcessInputRow(Input0Buffer Row)

  {

  /*

  Add your code here

  */

  //currentReceipt = Row.BelegKey;

  currentReceipt = Variables.receiptKey;

  newReceipt = Row.TransactionExtId;

  MessageBox.Show("The stored receipt key is: " + currentReceipt.ToString() + " The new is: " + newReceipt.ToString());

  if ( currentReceipt == newReceipt)

  {

  Counter++;

  }

  else {

  Counter = 0;

  }

  Row.Position = Counter;

  }

  Any comment would be appreciated.

  Kind Regards
