Serial Number System Status

Hello,

When using a movement type (981) the serial number status is not being updated.

When the serial number is introduced in the outbound delivery the status changes (from ECUS to ECUS EDEL), but when the goods receipt is created, the status doesn't change and it should change into ESTO.

Does any one know what it's missing in customization off this material movement type?

Thanks,

Sónia Gusmã
