How to calculate sum of a formula field in crystal Reports

Question

In some inherited code  I see group headers footers have items like  Sum of  numcount    I cannot get the sum of a formula field  Any thoughts

The only reason that I know of why a formula wouldn't be available to summarize on is if it didn't reference any database fields or whose value wasn't dynamic throughout sections of the report. For example, if you have a formula that returns a constant it won't be available. Or if it only references a field that is set throughout the report and returns a value based on that field, like "if {parameter}=1 then 1" would not be available either.

In general, the formula's value should not be static through the sections of the report you're summarizing over (Though the way Crystal determines this is beyond me and this doesn't seem to be a hard and fast rule)

EDIT: One other reason why a formula wouldn't be available is if you're already using a summary function in that formula. Only one level of summaries at a time!

Assuming you are looking at the reports in the Crystal Report Designer      Your menu options might be a little different depending on the version of Crystal Reports you re using  but you can either    Make a summary field  Right-click on the desired formula field in your detail section and choose  Insert Summary    Choose  sum  from the drop-down box and verify that the correct account grouping is selected  then click OK   You will then have a simple sum field in your group footer section  Make a running total field  Click on the  Insert  menu and choose  Running Total Field         Click on the New button and give your new running total field a name   Choose your formula field under  Field to summarize  and choose  sum  under  Type of Summary    Here you can also change when the total is evaluated and reset  leave these at their default if you re wanting a sum on each record  You can also use a formula to determine when a certain field should be counted in the total   Evaluate  Use Formula

You Can simply Right Click Formula Fields-   new Give it a name like TotalCount then Right this code   if isnull sum count  YOURCOLUMN      then 0 else  sum count  YOURCOLUMN       and Save then Drag and drop TotalCount this field in header footer  After you open  the  count  bracket you can drop your column there from the above section See the example in the Picture

You can try like this  Sum  Tablename Columnname    It will work without creating a summarize field in formulae
