Reserved batch consumption

Hi All,

I have a case that batch of a component is reserved for order and the order is released. goods issue not yet performed.

When I tried to do the goods issue found the material was not in stock. On analysis found that the material with the same batch was consumed by 541 mov. type..

My question is if the batch is reserved how it gets consumed for other purpose and what configuration needs to be done to protect the reserved batch consumption.

I have searched various threads but was not able to understand it.Please help me to understand this.

Thank you in advance.
