Import Variables from a SDM Request

Hi,

Since I wanted to import variables from a SDM Request, I selected "Select_Request" operator. Then Configured the Properties as below.

Post-execution Code:

Process.affectedEndUserName = Process[OpName].SelectRequestResponse.UDSObject[0].Attributes[0].Attribute[0].AttrValue[0].text_;

(I have created the 'affectedEndUserName' variable in the Dataset)

Then started the process through SDM. The Process got blocked at Post-execution. Following is the Log.

Dataset After execution

Please let me know where I got wrong. Thanks in advance.
