Okay, wondering if someone out here has experienced this issue as I am having difficulty coming up with a solution. We have Tecsys(WMS) that we are implementing here and it will interface with Lawson of course. We have a process(IPA flow) that when a purchase order is changed in Lawson then the PO Maintenance trigger fires when a PO is released and sends updated infor to Tecsys - or whomever in your case. Currently when a change happens in Lawson(qty, cost, etc) I am just re sending all the PO information across each time. However now we have discovered that if a line on a PO is cancelled or deleted, then those changes only need to go across once. My issue is how do I determine if those changes have already been sent. Any ideas are welcome and thanks in advance.
