How To Fix M2644 - & : Key figure hierarchy is lower than characteristics hierarchy

SAP Error Message - Details

• Message type: E = Error

• Message class: M2 - LIS: Generating and updating info structures

• Message number: 644

• Message text: & : Key figure hierarchy is lower than characteristics hierarchy

What causes this issue?

A key figure should be updated by a certain document hierarchy.
However, the characteristics of the information structure are updated
by a higher document hierarchy by means of update type 'B' (data
transport).
The update may not be definite.
Example:
You want to update the key figure from the document item. However, the
characteristics are determined from the document header. This means
that a statistics update of the key figure occurs for every item in the
document. Thus the key figure is updated as often as there are items in
the document. The values are overwritten each time by data transport,
which means that in the end, the key figure contains the information
from the last item.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Choose a key figure from the same (or a higher) document hierarchy as
the lowest hierarchy of the characteristics.
