Hi there,
Following from the above comments, you will need to upgrade the IR 6.1B Release 2.1 vintage 97!, to evaluate the Adagio PO module. We have a utility that will allow you to convert a copy of your data (within Plus) but you really want to do this on a copy of your live data to see the beauty of Purchase Orders for Adagio. (I'm biased). There are too many features and benefits to not look at this POA software if you already have DOS IR.
Call myself or Ryan and we can help you out.
Regards,
Brian
