I am currently doing Period End processing for my company, and have successfully completed it for our active company. However, we have an old company we still do maintenance on in SAGE,  and while I was trying to change the Fiscal Period in GL I receive an error "The Integrate to Bank Rec is required." The checkbox for this is greyed out, but was also unchecked/Greyed out for our current company that I have already done this on. I am at a loss and would appreciate any kind of assistance.
