How can I calculate average time in Crystal Reports given a collection of different times?
Average Time refers to the average start time when a given doctor starts diagnosing patients. I only have 1 SELECT FROM WHERE statement and cannot INSERT data into any database table, so I'm unclear how to calculate this value.
I tried using a separate SQL Command for just this calculation, but the results weren't on the same conditions (WHERE statement conditions and current doctor name for each row). I also tried this formula but don’t know how to adapt it.
Use a Running Total.
If you group by doctor, all the individual times will show up as records in the details section. (Or you can configure this in a subreport if necessary.)
Then create a Running Total that summarizes the time value (no dates included), evaluates for each record, and resets on change of group (doctor). Place this in the Doctor's group footer.
Again, you can set this up in a subreport too if your main report can't be configured with this grouping.

I am having trouble showing the correct totals in my tableau worksheet.
I have supervisors that are part of specific zones that need to complete a certain number of tests in different categories. For example, supervisor 15716 must complete 8 tests in category 1. I need to show the target, which is a number stored in the database and show the actual number of tests in that category that have been completed within a date range. I have it working, but Im not sure if I did it correctly because I can not show any totals.
System target - number stored in database
CountOfSheetID - calculated field
Percent Compliant - calculated field
Try this approach -
First define a calculated field called [Within Date Range?] as
[Date] >= [MyStartDate] AND [Date] <= [LastSelectedDayOfMonth]
and put that new field on the filter shelf, only including data where [Within Date Range?] is True. (You could also just filter the [Date] field if that is flexible enough for you)
The you don't need the CountofSheetId calculated field at all. If you want to know how many records have a non-null value for [SheetID] within your date range, you can simply drop [SheetID] on a shelf and choose to treat it as Measure with the aggregation function COUNT()
Then just build your visualization to show the counts you want (not percentages, the actual counts)
Finally, you can convert counts into Percentages by clicking on the pills for your Measures and choosing Percentage under Quick Table Calcs. You'll want to experiment with the "Compute Using" setting to tell Tableau how to compute your percentages -- i.e. define percentage of "what".
Percentages are implemented as table calcs in Tableau. Read the help to understand table calcs, especially the description of partitioning and addressing.
Crystal reports don't let me use a custom count formula field to filter which transactions to show in a manager report.
I'm creating a Crystal report that team leaders are supposed to take out to see on how many occasions their employees have reported in sick. A record is only supposed to show if that person has reported in sick 6 or more times the last 12 months.
The report shows a record (a page) for each employee belonging to the managers organisational unit. Below the employee information is a subreport where I show the transactions from the salary/time system. Using select expert, I have filtered out the transactions that is supposed to show. I have then created a database field that count which day was 12 months back from today, and filtered so that only the transactions falling into this period shows.
My last problem is that I only want to show the record that has a minimum of 6 such transactions during the period. I created a formula field named #Antal ("amount" in Swedish) that simply counts the distinct number of dates in the "from"-date for the salary transactions I'm showing (since a change of law 2019-01-01 we needed to create a new transaction type, so some of the occasions after 2019 may have two transactions referring to one sick leave, thus I'm counting the first day of the period instead), DistinctCount ({P_LSTAT.P_SXXX06})
Now, the subreport has a new column with Antal (amount) that counts the amount of the desired salary transaction. I then try to use the selection formula to only show records where {#Antal} >= 6 but I get the following error:
This formula cannot be used because it must be evaluated later
Is there any other (better) way of doing this, or am I simply missing something?
For your selection based on {#Antal} >= 6 you need to use the group selection formula, not the record selection formula. Record selection is used to select records which meet the criteria before reading in the data. Group selection is used to filter out entire groups of records based on summarised values, after the records have been read in and the summaries calculated - which sounds like exactly what you need here.
The value of a Formula Field is out of scope when the Select Expert is evaluated.
There is no process for calculating the value of a Formula Field before it is printed within the section of the report it is placed. The Select Expert is evaluated prior to any section of the report being printed, so at this time all Formula Fields are effectively Nothing.
I want to sort my report by ticketCost, but the regular summary of sum is got the total of all record include duplicate records.
The left field is a Summary and the right field is a Running Total. Only the Summary shows up when I go to configure the group, it only allows me to pick the Summary.
How can I sort on a Running Total? Or is there some other way to use a Summary to avoid duplicated records?
Crystal reports have two stages: the Reading stage and the Printing stage. Your Running Total fields are evaluated during Printing, but Grouping occurs during Reading. This is why you can't group on a Running Total - it won't be ready by the time Grouping needs it to be.
The best way around this is to perform the calculations is to write a custom SQL statement in the Database Expert.
This will return a new table in which you can calculate ticketCost as a field even before it reaches the report. Then group based on the new ticketCost field.
I've been working on a report that uses subreports to print records.
The problem is: for the same information, there may be several records - i.e.:
There may be several records for the same product if those records differ in one single column. My goal here is to make a Record Selection Formula that says: "if that item is already shown, then don't show it once again."
I've tried to use (shared) variables for this, but can't seem to find the way, because of the evaluation time.
Selection formulas are already being used to apply some filtering criteria. The column that may differ between two ocurrences of the same record is not always the same, so using a simple Selection Formula is not likely to work...
Any suggestions?
Example:
I used the record selection to tell the report:
"Show me all the products according to these criteria (warehouse=parameter1 and category=parameter2 for example)".
But there may be more than one record for the same product of the same category and inside the same warehouse, if one or more fields are different (for example, different price, different lot)
I want not to display those repetitions.
Your approach is wrong... Record Selection Forumula is something that is applied at report level not on the row level or column level.
If you requirement is not to show the records that duplicates then you need to write the supress condition for those, As per your requirement apply supress condition to the rows or columns.
I have a report that I've written and I understand how to create running totals and such, but need help creating a custom evaluation formula.
I have two levels of groups, first group is based upon a certain user, the next group is based upon transactions that user has been involved in. I have details hidden, and am only interested in the totals for a particular activity. This is working great, and totals are working properly but the problem is, each activity has a 'line number', which essentially can be the same as another activity (ie: two activities can have lines 1, 2, 3 contained within), so doing a distinctive total based upon a set of data isn't accurate because I only want it to be distinct based upon each individual recordset, and not globally.
The example is below... if I do a count on each record for this dataset, it comes out to 18 because there are duplicate line numbers on each... but if I do distinct, it only comes to 9 because of duplicate line numbers across multiple actives.
I guess what I need to know is how I can take the totals per detail group, and have them total up in my second footer properly. I assume it's going to take me compiling together a string including the activity number and line number, and then comparing them?
Here is an example of the data contained within the total groupings:
I figured this out on my own... turned out it was pretty simple. I converted my numeric values to text, and included a copy of the transaction id and the line id as my test value, and did distinct on that... Sometimes it just helps not staring the problem down.
