Presales isn't really designed to create sample workflows like this, but we're more than happy to help you with any areas of difficulty that you're having! It sounds like you're having trouble getting started, so I would suggest creating a metadata field for the status codes. Then create a workflow will likely contain the following:

1) A "Find Entries" activity that will pull the documents that you want to compare

2) A "Retrieve Field Values" activity where you will retrieve the status code from the metadata field that you created

3) A "query data" activity where you retrieve all the document names and status codes for each document.

4) A routing decision (This will likely be inside of a "For each entry" activity) that will have 2 branches:

a) One will be satisfied when the document name is matched in the database (Also in the "For Each Entry")

I) Another routing decision that will have 2 branches (Also in the "For Each Entry")

i) One will be satisfied when the status code of the document matches the status code in the database

ii) The other will handle documents whose status code doesn't match

b) The other will handle exceptions if the document name isn't found in the database

Hopefully this is enough to get you started! The configuration of each activity will be up to you due to the fact that we aren't aware of how the system is set up and the exact details of each activity. If you run into any problems or if you have any more questions, feel free to let us know!
