So I have been trying to create this process flow - with the help of some amazing developers at Thinkwise - that checks if there are documents uploaded and based on this decision, show a warning message that the user forgot to upload the documents (don’t show any warning if there are already documents, instead run the main task immediately).
So my process flow looks like this (see images through this link https://imgur.com/a/QqBVNpQ). I created a ‘fake’ process action Ready_for_billing_outbound_order (the first one) I give it two output task parameters: outbound_order_id and documents_complete.
I linked this to a decision with no input or output, just a functionality (see third image). Based on the if statement, either the warning is shown or the task runs.
The problem starts when I try to run a creation, I get error(s) and one of them is: No declarable variable @execute_tab_task_outbound_order_check_show_msg_no_proof_of_delivery_invoice
How does this process flow work and what do the error(s) mean?
