What causes this issue?

You tried to create an allocation table in manual planning. In doing
so, you create the material group as a planning level. When the items
for the allocation table were created, material &V3& was added. The
material master for material &V3& includes different material group.

System Response

The allocation table was not created.

How to fix this error?

For planning reasons, you can assign a material group that is different
from the master data to a material in the planning hierarchy. When an
allocation table is created in manual planning, active processes such
as purchase orders and deliveries are included, resulting in
consistancy with the master data. For this reason, check the material
master data or do not run planning for material &V3&.

  During material planning or MRP runs.
