Re: Re:

Good so in the Logical i have it seems that the logical returns all of the
fields of the Physical, lets say 100 fields. WHen we may be using only 3
fields in the Crystal. Are these extra 97 fields going to cause a slower
performance or its not an issue as number of records are.

In the past I would create a Stored Procedures on the IBM I using either
SQL or RPG to select and generate only the records I wanted on the CR. This
greatly improves performance of CR since all the selection and number
crunching is done on the IBM i and not on the local PC by CR.

The few times I have used CR to access data on the i, it was done using the
PF in a subreport. All the PF fields were available. I would assume that
a LF would only return the records it referenced and then only the fields
that were defined in the LF DDS.

It seems to me, if I remember, the logical file, when used in Crystal
REports, it passing not only all the records of the file OEOEHDOH, but

also

all the many fields. Is this correct?
If the CR only is interested in say 5 fields, how can we code this

logical

or to make a new one that will only pass less, is that a performance

issue

would you say?
I have also added a temporary filter to this logical
