stock quantity

Dear All,

I have a material where QM is activated.

it has some quantity in the quality inspection stock which i did UD and sent to unrestricted use stock.

now i need to do some change in the MMR but it is displaying error that plant stock exist.

when i saw the MMR it is showing that the same quantity is present in In quality inspection at Plant stock in previous period.

How to clear this quality stock to unrestricted stock in the previous period?presently there are no inspection lot in QA32.

Regards,

Indranil
