Hi Zoey,

Check out Sage knowledgebase article: How to correct orphaned allocations. (16964). If those steps don't allow you to deallocate the stock, I would suggest contacting your local Sage Support team or your Sage business partner for assistance.

If reply does help you resolve your issue, please mark this as "Verified Answer" for the benefit of future readers.

Thank you,

Thanks for your response! To be honest, I am asking here because our Sage provider told or suggested to us that it was not possible, and have made no attempt to fix it since the first report of this issue almost a year ago haha. I am running the process in simulation mode, but it's still thinking after 2 hours of processing... How long do you think it'll take for 3 years of records?

Hi Zoey 

We can reopen the sales order then de allocate the stock then close the order 

VeNu BaBu This would be an amazing solution. Can you let me know how?
