SAP Error Message - Details

• Message class: NAA - Subsequent settlement (Purchasing)

• Message number: 084

• Message text: Error during unit conversion of business volume for scale basis

What causes this issue?

Translation: Largely identical to NAA085
The business volume for the scale basis (see calculation rule) is taken
from the document conditions in unit &V1&. However, as the update of
business volume data is to be carried out in unit &V2&, conversion is
needed.
However, it is not possible to convert units &V1& and &V2&.

System Response

Business volume data is not updated, as the business volume for the
scale basis is missing.

How to fix this error?

Ensure that the system is able to determine the business volume in the
form given above.
For this, the gross/net weight, volumes, points, and the required units
of measure should be maintained in the material master, and/or a
suitable unit of measure conversion should be defined in the material
master (alternative unit of measure) or info record (conversion of order
unit according to points).
The data can be copied from the material master and info record to the
document item and changed. The system attempted to use this data (item
data, info record, material master) to carry out the conversion, but
this attempt was unsuccessful.
If necessary, contact your system administrator.

If you have the necessary authorization, you can maintain the material
master directly.
