We are in the process of migrating historical data from a
Japanese subsidiary into our JDE system, and we have found
that some of their files have invalid data in some of the
fields. I would like to be able to write a program that
can identify which fields in which records have
potentially invalid DBCS data.
The files in question are CCSID 930.
Invalid in what sense? Some examples might be helpful. What
error(s), and under what circumstances?
If the /invalid/ implies a data mapping error occurs for some
data conversion\map operation, then the mapping error should
identify the row in error. A CPYF or a SQL query which maps the
column\data to a compatible data type & CCSID could record the
mapping errors with relative row number. By review of record number
causing the error, update those rows with the expected\valid data.
The mapping could be defined in an LF instead of a query, that LF
accessed by a program for RLA, could enable another way. Note that
there can be no selection on the column if there is a mapping error
evaluating the criteria, because the database can not conclude if
the data should be omitted or included; i.e. any result set based on
an inconclusive selection test would be inherently incorrect.
