Hello,

you are right not to use NULLIF in the layaout definition. But you can use a CASE statement when you use the data

> .FIELD  TT_STAT_TYP                  424
> DECIMAL(15,0)
>         NULLIF TT_STAT_TYP_IND       = '?';
> .FIELD  TT_STAT_TYP_IND              432  CHAR(01);


INSERT INTO ....
TT_STAT_TYP = CASE WHEN :TT_STAT_TYP_IND = '?'
                                        THEN NULL
                    ELSE :TT_STAT_TYP
              END

This will not have the terrible effects on CPU you try to prevent by not using NULLIF.

Hope this helps!

Thanks!
