• Message text: Supplier business volume for scale basis could not be determined

What causes this issue?

The reference value &V1& specifies the form in which the supplier
business volume is used to determine the scale level (scale basis).
However, the system was not able to determine this business volume
magnitude from the data of the purchasing document item.
An attempted conversion from the order unit of the PO item into the unit
&V2& of the scale basis was unsuccessful due to the lack of suitable
conversion factors.

System Response

The function you called cannot be performed for this transaction. The
scale basis needed for settlement accounting purposes could not be
determined.

How to fix this error?

Make sure that the system is in a position to determine the business
volume in the above form.
To do so, you should maintain the gross or net weight, physical volumes,
points, and the required units of measure in the material master record,
and/or define a suitable unit conversion in the material master record
(alternative unit of measure) or info record (conversion of order unit
to points).
If no material is available, you may not be able to use the condition
record in the existing form.
The data is transferred from the material master and info record to the
document item where it can be changed manually.
With this data (item data, info record, material record), the system
tried to carry out the above conversion, but was unsuccessful.
If necessary, contact your system administrator.

If you have the necessary authorization, you can maintain the material
master record directly.
CALL "CHANGE MATERIAL MASTER" TRANSACTION:

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