Bulk material not allowed for items relevant to costing

What causes this issue?

You are processing an item which is relevant to costing and want to set
the indicator for bulk material.
Bulk material can be made directly available at work centers. However,
as it is only of low value in small quantities, costing of bulk
material for orders is not supported.
Therefore you cannot set the indicator for this item.
