Re-open Reservation after component scrap during production

Hello Experts,

We have a scenario where the production deals with unplanned component scraps.

For ex: a production order has a component requirement of 100 pieces. Once this order is created, the 100 piece reservation can be seen for the component. After material staging and GI the reservation is closed against the component material.

During the order confirmation production has issues with the components and decides to scrap 50 pieces from the orignal 100. We use 531 to bring it back in 901 and later scrap them.

Now is there a way to open the 50 pieces which were scrapped so that MRP considers this 50 pieces which are still requried to complete the production order ?

These are not planned scrap quantities so we do not maintain any %s in the master data.

Thanks,

Sandeep
