The error here states the the Sub Analysis that has been entered for the referenced stock item does not exist.
This may mean you need to create the sub analysis, or that the sub analysis has been misspelt in the source file.
You can check the sub analyses against a stock item:
Click Stock Control, Stock Records
Search for the stock item in the error message
Click Sub Analysis
Note down the Sub Analysis Code you want to use.
Update the source file for Transaction Broker to have the correct Sub Analysis code and upload again.
