Hi @Ionut_Istrate

please initialize the TransactionNumber with 1 and try once again.

based on that you are page numbers processed, if you leave it null it throws an error.

thanks

i guess you have not passed arguments to GetTransactiondata(), can you verify once…

in_transactionNumber = TransactionNumber

This is my Get transaction data… i don t know where i need to change the values

GetTransactionData.xaml (10.9 KB)

GetTransactionData.xaml (10.1 KB)

in that case put a breakpoint to Gettransactiondata workflow and use debug mode to see whats the prob…

thanks

Please verify that you have value in in_WIList in GetTransactionData.xaml if there no value see that you have extracted and sent the WILIst items correctly. In InitState like this
