You can roll up manufactured parts with the global update however purchased items do not roll up. I am looking for a way to do this automatically
I had asked the same question of our SAP consultant and obtained the following reply,
There is the menu item to "update parent item prices globally" but it does not update the lower levels to the upper BOM levels.
The way we currently do it is to start at the lowest level BOM, roll up, update, go to the next and so on to the top level.
We have been told this is the only way to handle this process.
