Each of the Workbench Export scripts creates data in the MYOB Category field for each transaction line. This has been done to create a field for audit referencing when you use the MYOB ODBC.
When MYOB imports the batch of data it validates this category so these codes must be setup in MYOB before anything can be imported. It is a different code for each type of transaction.
These are the codes that will need to be setup. These are case sensitive. Be accurate when loading.
