How do i suppress duplicates within a report if those duplicates are not consecutivly listed. (for consecutively listed reports I can use either the suppress duplicates checkbox for the field or use a Previous field formula.
E.g. Report with 3 fields    A          B          C    
    Brings back                  (A1)     (B1)      (C1)
                                      (A1)     (B1)       (C2)
                                      (A1)     (B1)       (C3)
                                      (A1)     (B2)       (C1)
                                      (A1)     (B2)       (C4)
                                      (A2)     (B3)       (C1)
                                      (A2)     (B2)        (C3)
I would like to only display each return once so that report above looks like
                                      A          B          C    
    Brings back                  (A1)     (B1)      (C1)
                                                              (C2)
                                                              (C3)
                                                 (B2)      
                                                               (C4)
                                      (A2)     (B3)        
                                               
Can I achieve this witha suppress field formula?

You can probably do it, but it'll be messy.  I don't have access to Crystal at the moment so some syntax may be off but basically you want to write a formula that's really a mini-program...

//@InitFormula  <- Place in report header
shared numberVar NumDistinct := 0;
shared numberVar array FieldAList[100];   <- Assumes field A is numeric, use appropriate data type

//@SuppressFormula  <- Use to conditionally suppress field A.
numberVar i;
booleanVar DupEntry := false;
if shared numberVar NumDistinct = 0 then
(
   shared numberVar array FieldAList[1] := {table.fieldA}
   NumDistinct := 1;  
)
else
(
   for i = 1 to NumDistinct
   (
      if shared numberVar array FieldAList[i] = {table.fieldA} then DupEntry := true;
   )
   NumDistinct := NumDistinct + 1;
   FieldAList[NumDistinct] := {table.fieldA};
)
DupEntry;

Follow the same process for the other two fields and you should have them suppressed - as I said, it's messy...

Do you need the format as shown or will something like this work?

      A          B          C    
    (A1)     (B1)      (C1)
    (A2)     (B2)      (C2)
               (B3)       (C3)
                            (C4)

If so you could use subreports for each column and use the Select Distinct capability or suppress duplicate records.

Also I didn't ask about your data source.  I believe the absolute best method would be to use a stored procedure and filter out the unnecessary date before it even gets to Crystal.

If you're already using a SP or have the option of doing so then I'd advise taking this route.
