Sales order- stock- Batch

Hi

I have created a new plant abcd.

At all our old plants Sales orders take quantities only from free available stock- unrestricted stock and do not pick it from Restricted Stock.

But from new plant abcd something does not work and sales orders pick quantities from restricted stock.

Request you to please let me know why sales order pick quantities from Restricted stock form plant abcd?

Thank you very much in advance.

Regards
