& (identify via non-history table field KALN1: & ), LFMON: & , LFGJA: &

History tables (MBEWH, EBEWH, QBEWH, OBEWH) do not contain the field
KALN1.
Consequently, you have to enter the corresponding non-history table
(MBEW, EBEW, QBEW, OBEW) with the corresponding KALN1-field in
transaction SE16H.
Afterwards you retrieve the table key, which is identical in the
non-history and history table.
If you want to compare the data with the original database table before
migration, enter the database view MBV<Table_Name>OLD (= CDS-view
accesses data before data migration), for instance MBVMBEWHOLD for table
MBEWH.

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