Picking completed even without stock balance

Hi All,

I created an OBD and 'TO' was alos created and I even confirmed TO. Now "Overall pick status" shows "fully picked" in VL03N. However Stock balance is still "zero". How is this possible? What could be the settings for this?

And why the status is fully picked when I do not have material physically at my warehouse?

Please also let me know how to stop creating TO if I donot have stock available

Thanks,

Shetty
