BOM is recursive

What causes this issue?

You want to enter a material component and you have entered a material
that causes <DS:GLOS.recursiveness>recursiveness</>.

System Response

The system checks the <DS:DE.REKRS>Recursiveness allowed</> indicator
for the BOM item. You can use this indicator to switch off the
recursiveness check.

How to fix this error?

If you want to enter the component that causes recursiveness, set this
indicator.
