how to set Error on truncation in informatica

问题

I'm just new in the informatica and I want to set a data loading that will handle error checking.

E.g I have char(1) data type in the Recepction Table now, in my source I have more than 1 char but informatica is loading the data and it is being truncated in the reception table.

I just want configure the loading that my session will fail if there is truncation happen from source to reception.

By default, when a value is truncated, a warning is logged. If you want to treat truncation as an error, select the option Reject Truncated/Overflowed rows in the target definition.

If rejecting the problematic rows is not enough, you can configure the session to fail by setting the non-fatal error threshold to 1 (option Stop on errors).

If you need to monitor only selected columns, use the following expression for each of them:

out_OneCharColumn = IIF(LEN(in_OneCharColumn) > 1
                      , ABORT('Source value would be truncated')
                      , in_OneCharColumn)
