We assemble large machines and we want to be able to allow time in our production planning for picking and placement of the components on the shop floor prior to assembly.
How do you suggest we best allocate the time for picking to the production order so that material is available in time for the actual assembly operation to begin?
The picking process takes around 4 days.

hi, you can use wait time, queue time, and move time for that,
and in the BOM, you can link between material and the operation, so that the planned issue date will be more accurate.
