Subject: Number Range interval deleted automatically

Question

Hi
At the time of Accounting Document Posting system is giving error message for maintaining number ranges interval for the corresponding Number Ranges (For example: 50, 51, 49, 19) for the fiscal year 2010. But Number range interval has already been maintained in the Tcode FBN1 for the fiscal year 2010.
After maintaining Number range interval again for the corresponding number range in Tcode FBN1, when we are trying to post accounting document system is again giving one error message that document number (5000000000) is already been used. When we are looking into Tcode FBN1 the current number status is 0.
So to resolve this problem  we have to provide the Number range status into FBN1 manually (suppose if 10 doc are already existing in the system for number range 50 then we have enter the number range 5000000010 manually in FBN1).
After Number range status setting in FBN1 System is allowing to post the Accounting Document.
Along with this one more issue is appearing related to MM posting period. 
The current posting period in the system is 08/2010 and the initial period in the system is 08/2007. System is automatically going back to the initial posting period 08/2007. After opening the Posting Period with Tcode MMPV we can post the document only.
Both Issues are appearing repeatedly.
Plese help
Thanks..

Dear If you have already maintained number range for particular period then again for same period and series system should not allow to maintain but as you said above it is allowed so i feel it was not done correctly first time and the given series number could have already been used so when changed the current number in status it's working fine.
For  MM posting period issue please check transactions MMRV,OMSY,OMWD with your MM consultant
Cheers
