We upgraded to SL 2011 about 6 months ago. In the 5 years we've been Dynamics users, we have consistently used just a few kits with no problems. It appears that since upgrading, inventory items used in the kit sit in "On Open Shippers" in inventory which throws off availability. The made product is just fine. I am able to clear via inventory integrity by running each individual item for the site, but this isn't a good long term solution. I do remember that when we upgraded, we had several interruption errors that referenced the SO plan and I am curious as to whether they are connected. I'm not as familiar with the SO integrity check, or the potential harm I can cause (I'm defacto system admin, we are a small company with no IT team). I do know enough to get everyone off the system and shut down process manager. Just wondered if anyone else has run into this issue and what can be done to resolve it. Thanks.
