Method &1: source assignment: incorrect item type in item &2

What causes this issue?

In step &V3& of reclassification method &V1&, you have specified the
item &V2& as the source assignment. You have assigned this
reclassification method to reclassification task &V4&. In this task, you
have selected the <LS>Assets Held for Sale</> checkbox.
When you define the source assignment in the reclassification method for
this type of task, the item type depends on the setting that you
selected for <LS>Processing Type of Assets Held for Sale</> in the
reclassification method:
If the processing type is <LS>Consolidation Units Held for Sale</>, <LS>
Partner Units Held for Sale</>, <LS>Discontinued Consolidation Units</>,
or <LS>Discontinued Partner Units</>, you should not specify an explicit
source assignment.
If the processing type is <LS>Equity-Method Investee Units Held for Sale
</>, you must use the items <LS>Assets Held for Sale</> or <LS>
Liabilities Held for Sale</> as the source assignment.
The item type for item &V2& does not meet the above requirement.

How to fix this error?

Adjust the Customizing settings for the source assignment in
reclassification method &V1& as outlined above by making sure you only
define items with an appropriate item type as the trigger.
