R12.1.3: Invoice adjustments blocked for inaccurate accounting

Sometimes when searching for one thing, you find another, and the article "Invoice Adjustments Ends in Error - This Action Has Been Blocked To Avoid Inaccurate Accounting Entries" via document ID 1626521.1 is no different.  I am lucky that we haven't had any reports of the error "This action has been blocked to avoid inaccurate accounting entries" being encountered yet, but I am going to be checking the version of ARALLOCB.pls that we have in our system to make sure that we will not be getting it in the future.  Will you be checking as well, or will you encounter the issue when you can least afford it?
