Using Summary or Formula fields based on what a string field has.

Question

Attached is an example report that was not created by Crystal Reports.  I am working on re-creating it in Crystal Reports.
I am using Crystal Reports 2011.
The Total line for each group of details needs to have sum total fields for only items for pieces, weight, etc. whose Serial No does not begin with B.  How do I do that?

Answer 1

Hi Keith,
Create a formula that defines a variable we will use.  This will go into a group header and resets the variable to 0 when the group changes.
@intialize
WhilePrintingRecords;
NumberVar myTotal := 0;
Drop this into the group header of the group where the total will appear.
Your second formula will do the summing and goes usually goes into the Detail section:
@process_records
WhilePrintingRecords;
NumberVar myTotal;
if left (Uppercase ({table.FIELD}), 1) = "B" then
    myTotal := myTotal + {table.numberfield}
Else myTotal;
So this formula checks your field for the letter B.  You may not need to use Uppercase.
The last formula will go into your Group Footer where you want your total to appear like:
@showtotals
WhilePrintingRecords;
NumberVar myTotal;
And that's it.  Notice the variable is populated with := and not just =.  The single = is a comparison so make sure you use the correct on.
Good luck,
Brian
