Conversion factors for material master record - info record are different

What causes this issue?

The conversion factor (used to convert from the unit of entry to the
base unit of measure) contained in the consignment or pipeline info
record differs from the conversion factor specified in the material
master record.
The conversion factor may have been changed in the material master
record but not in the info record.

System Response

Depending on the system configuration, this message is either a warning
or an error message.
The system determines the pipeline price on the basis of the conversion
factor in the info record. However, the entry quantity is converted to
the base unit of measure on the basis of the conversion factor in the
material master record. As a result, the goods movement could be
valuated at the wrong price.

How to fix this error?

Check the conversion factors in the material master record and in the
consignment or pipeline info record.
-> <DS:TRAN.MM02>Display material master record</>
-> <DS:TRAN.ME13>Display info record</>
If you have to change the conversion factors, cancel current processing
and change the material master record or the info record.
