Equipment/usage ignored

What causes this issue?

You want to edit the BOM group of an equipment BOM. In the selected
plant, the BOM group is identified by either the name of the BOM group
or the equipment and BOM usage.

System Response

If you enter the name of the BOM group, the system finds the BOM group
using this name. If you enter an equipment and usage, the system does
not check your entries.

How to fix this error?

Confirm by pressing ENTER.
The system deletes your entries in the fields <PF>Equipment</> and
<PF>Usage</>.
If the BOM group you entered is not correct, you can identify the BOM
group by entering an equipment and BOM usage.
