Michele, thank you for sharing. All resource issues aside I also felt there was very poor quality control on the SAP side. In the first delivered version there was actually a typo in the XML structure - how could this not be caught?
From my experience, it's much cheaper to make effort initially and get things done right first time. If there is a resource shortage then at least those resources should be spent wiser.
I'll close this thread when the saga is over (the deadlines have been moved several times by government and some corrections are still in progress). On a bright side - some solution has been delivered by SAP, so we're not completely dead in the water. But definitely there are some "lessons learned" to be looked into.
The silver lining here is how the SCN community came together to help. At least we have each other! Image may be NSFW.
Clik here to view.
