    Unanswered: Counting Unique Records For All Groups

    Hello All,

    I am trying to find the best way to sum the count of all records that appear across multiple groups.

    To explain what I am trying to achieve we may have two groups in a report that both contain the same record, i.e.

    Order 1
    Part A
    Part B
    Part C

    Order 2
    Part A
    Part B
    Part D

    I am attempting to generate a total at the report footer, that will contain a summary to the effect of:

    Part A: 2
    Part B: 2
    Part C: 1
    Part D: 1

    When looking at our order history, I am attempting to see how many times Part A occurs with Part B on the same order. Because of this I have grouped the information by the order number record and used a selection criteria, this prevents me simply grouping around the part number field and using a count.

    I could use a formula and manually enter a sum if part = A, however I'm trying to evaluate against approximately 10,000 records (different part numbers), so that would be prohibitive.



    Manually I have exported the report without a total to Excel, and used Excel's Data Validation to show only unique records, and then use a COUNTIF statement to generate this information, however it is a manual process and would like to achieve a result inside Crystal Reports.

    Is this possible, or am I barking up the wrong tree? I don't mind being advised to research certain topics if someone could point me in the right direction.

    Thanks in advance!

    Without knowing more about your Crystal Reports version and the structures of both your data and your report, I can't offer you a good opinion.

    If your version of Crystal supports sub-reports, then that's likely to be the easiest answer. Just create the sub-report of part counts (as simply as possible, little or no formatting) and include the sub-report in your current report footer.

    In theory, theory and practice are identical. In practice, theory and practice are unrelated.
