We were going down the same path, but my database team is telling me that we cannot use RQ500 since our version of Lawson will not take the CSV file. We are on Lawson 9.0.1 msp7, but they are saying it requires a patch which makes so many changes it might as well be an upgrade. Surely people were loading outside requisitions on v9 and earlier. There has to be a way or am I dreaming?
Thanks!
I created the interfaces between Lawson and a different RFID system. The standard interfaces like RQ500 will work and are in your best interest: you have to be thinking about the cost and complexity of long term ownership. Custom interfaces are expensive and often cost-prohibitive.
The key issue is an understanding of the architecture of the systems. It is unlikely that you are going to transact and track your inventory in Lawson at the GTIN level (as a general rule); whereas, an RFID system will probably want to work that way. Therefore, when you integrate your setup and your primary keys for entities like locations and basic transactions like receipts will have to translate appropriately.
I don't know the Cardinal system, but a quick insight can probably be achieved by walking through the REQ to check process for a simple transaction. The interaction between the two systems, particularly when the receipt happens will be revealing.
