Sales Order Overall Status

My overall status for my sales order is not shoing as being completed. My item category that is the same in each sales order is a non tangible item and will need to be split into different delvieries at times so the completion rule for this is B and the billing relevance is A...the sales order does indicate the delviery status as complete...the accounting document is cleared but for some reason my over all status is "being processed" has anyone ran into this before? What were the corrections?
