customer consignment stock available, but cannot confirm quantity

Hi

In MMBE, the system shows stock under the Customer Consignment. But when we do Availability Check for an Consignment Issue order, it shows the confirmed qty. as zero.

The Consignment Issue and the Stock blocked under MMBE is for the same customer.

I dont have any other open orders for this Customer and Material, except for the one i am trying to do Availability check.

Else, as per the Availability check, if there is no customer consignment stock, then why is stock shown in MMBE?

Regards,

MM
