PPC1DM030 - Overview

• Message type: E = Error

• Message class: PPC1DM - PP Backflush: Database Management and Communication

• Message number: 030

• Message text: The unit of measure &1 cannot be converted to &2

What causes this issue?

The material &3& in plant &v4& has the base unit of measure &v2&.
However, the backflush took place using the unit of measure &v1&. There
is no conversion relationship between these two units of measure.

System Response

The system always uses the base unit of measure when backflushing. If
it cannot convert to this unit of measure, it rejects the backflush.

How to fix this error?

- Check whether the backflushed unit of measure is correct
- If necessary, maintain alternative units of measure in the basic data
of the material master for &v3&
- If necessary, check that the conversion from an ISO unit of measure
to the unit of measure &v1& is correct
- Check whether the units of measure mentioned are in the table T006
