Move first date in sales order

Hello,

I have cases where we have first date in sales order line eg. 01/03/2016. But due to the customer returns the material is available on 15/01/2016. How to make system go through all the sales orders and check ifthe material is available earlier and if yes, move that date to eg 15/01/2016. The jobs V_V2 and SD03 do not do anything to the first date. Does anybody have an idea ?

Thanks a lot. I have searched the forums but have not found anything similar.

Regards,

Olaf
