Unable to generate accounting docs for invoice.

Question

hi all,
I have a delivery related  billing invoice created in May 2010 that we're attempting to cancel.  We created a MIRO invoice against a sales generated PO tied to the Sales order for the invoice.
Subsequently, in August, we determined that we needed to cancel the MIRO invoice, and discovered it's necessary to reverse the sales order Invoice first (subsequent docs.)
In attempting to cancel the SD billing document, we received several error messages that prevented the creation of the invoice.  We were eventually able to create the invoice by changing the billing date to the current date (from the defaulted may date) and things got interesting.
We created a SD cancellation invoice in Aug  but were not able to generate accounting docs
I thought that if we updated the billing date to this month we would be able to process.   So updating the billing date to 09-13-2010 (today) I receive this error
System error in the FI interface
If we modify to any date before September, we receive the following error message, which we expect, since we've closed prior period.
Posting period MMM YYYY is not open  (billing dates attempted - 07-31-2010, 08-05-2010, 8-31-2010)
If i process using a september date, the changd date is not retained.  only non september dates (also attempted 10-1-2010) are retained.  This leads me to believe that there's an issue that's outside of the billing date causing the problem.
Can someone provide some input on how to properly address this invoice and allow it to generate accounting documents?

You could be encounrtering related FI errors. Release your billing document in VFX3 and refer to the details in the error logs.
