Deficit of BA Unrestr. prev. while doing MFBF

Hi All,

I am stuck in a problem while doing MFBF transaction.

I am trying to book consumption entry for the month of September ( Posting date : 30.09.2015 ) in the month of October ( today).

While doing so system is not allowing to post the transaction. Its throwing error saying

"Deficit of BA Unrestr. prev. 190.700 TO : 201094941 2073 PDS1 PRCMIND"

I have check the stock in MMBE and MB5B transaction and seen that there is enough stock to consume. Even the period for the month of September and October are open.

Requesting you to please guide on the same.

Thanks

Mehul
