MA807- error message while running the MC87 transaction

Hi,

while running the MC87 transaction for a Finished material, encounter the message <Invalid date>

of MA807 error message.

It was working fine 2 days back.

For the corrective action, i have gone through the SAP note 947082. But how can i resolve this?

Can i ask Basis experts to help/ apply this notes?

thanks,

Sonai
