Re: getting sql error

I had to add a filter for warehouse. Suddenly I am getting a null error,

and idsrom in (100, 114)
GROUP BY rollup(IDIDAT)
the error is this:
Message . . . . : Data mapping error on member FBA.

Cause . . . . . : A data mapping error occurred on field SEL0002 in
record
number 0, record format FBA, member number 1, in member FBA file FBA in

library QGPL, because of error code 20. The error code meanings follow:

20 -- A field that is not null capable could not be set to null.

The SQL diagnostic messages aren't always as helpful as we'd like, but
this one is OK. What happens if there's a day (IDIDAT) that has no
invoices with an order type of FB? You'll get a value for the date, and
a null for the count of invoices. Read up on COALESCE.
