Hi, I have done all the points in this exercise that is about setting the settings up. When I run the main workflow I get an error message (see attachment). But when I run all the Workflows one by one manually the work fine. Please help me understand this problem. Regards, Mikael [mainError]

I am guessing it too. Have tried to find the problem, but can’t find it. I know it is just a little peace that i have missed…

Do it step by step - See that the data you have scrapped in ExtractWIDetails.xaml workflow have the DataRow Then Assign that to a local variable in Main.xaml in WIList of type DataRow (that you have already done I guess) After this Send this WIList as in argument to GetTransactionData.xaml like i…

[image] [image] This is what i’ve done…

Are you using the argument directly as the output of the data scraping? If yes, try using a variable there with default value New System.Data.DataTable, then assign this variable to the out_WIData*whatever the name of your argument is) argument.

I am using the ExtractDataTable variable that comes from the Scrapping and then assign it to WIList that has value DataRow and then I assign WIList to out_WIList argument with value DataRow like in this screenshot that I even posted before. [image]

[image] Niket_Ghai: default value New System.Data.DataTable, Assign this to the data table before scraping :slight_smile:

Now it goes further :slightly_smiling_face: but i use a messagebox to show the data from the DT but it is null. It goes through all the data at all pages but does not save the data. :thinking:

Perform the data scraping again. Might work

I didn’t Work. I performed the scrapping 3 times but still data table is empty. Here is the error message. According to this the dt is empty because the it can’t get the id right? [image]

Try debug mode, to see where the problem is.
