SAP Error Message - Details

• Message type: E = Error

• Message class: HUFUNCTIONS - Messages from FB with HU services without global t.

• Message number: 314

• Message text: Packing proposal is not unique - there is no identifier

What causes this issue?

The handling unit has a header record that has a blank
<DS:DE.EXIDV>external identifier</>. Therefore, the system cannot
clearly identify this record, meaning that no assignments to existing
items can be made.

System Response

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?

Make an entry for the identifier in the header. If you want the system
to assign numbers, use a '$' sign as the first character of this field.
All identifiers that begin with a '$' sign will be reassigned by the
system.
If the first character is not a '$' sign, you must use a number from
the external number-range interval that corresponds with the number
assignment for <DS:DE.VHIART>packaging material types</>.
