overall delivery status - block

Hello,

Could you please help me with my problem.

I have in sales order on header level the overall delivery status block active and have no idea where it is coming from.

As i have checked the changes there was z delivery block which was then removed and it seems the headeroverall delivery status was not updated .

Could you please explain if it can be a program error and how to deal with it. Maybe do you know any SAP notes for such cases or program that can update the tables.

I have spend a lot of time but did not succeed

Thank you for help.

Regards

M.
