Not able to call Parameter value from Dashboard button to DM Seq

[pranav46]

Can someone please guide me on passing parameter from dashboard button to DM seq. I followed couple close forum question but still it did not work.

Basically trying to call DM seq which has extensibility rule from button. Some how it not able to read value from the parameter. Could you guide me what I am doing wrong.

Trying to capture value here. It work if I just execute DM but does not from button. 

Dim DimTypeStr As String = args.NameValuePairs.XFGetValue("EnterDimensionType", String.Empty)

Calling a parameter in the Selection Changed Server Task Arguments must be done using pipes also. Change it to {Export_Data_To_File}{EnterDIMType = [|!DimensionList!|]} and try again.

Thanks for responding!

It did not work. Just does not pass value from button to DM SEQ.

You will need to reference the parameter in the DM Step and not the sequence in this case.

I figured it out.
I had to put space in between my parameter value and removed parameter from DM SEQ. I left it blank and value is being passed from Server action.
