problem with error "Posting periods not open" in billing
I have a problem with a Date in transaction Code VA01.
Here we can able to setup different billing dates in Test run.
But in actual posting periods.... it is not working.
i can go to an explaination by taking the realtime scenario..
Bill generated on 30.10.2007
The bill to be posted on 16.06.2008.
While posting on 16.06.2008 it is throwing an error that ""Posting periods Not open""
what should i do to post the bill.
