I have a Jasper report that displays a list of bill line items. These items are grouped by billing period, and then by whether the item is a charge or credit. For billing periods in which there are charges but no credits, I would like to display a static text field stating "No credits" in the Credit group for that period. How can this be done?
Edited to add: This is assuming that I am using an SQL query for the data source, as opposed to customizing one. If I customize my data source, I can handle this in pre-processing before I reach the report, but I was hoping to discover a way to get around Jasper's behavior of skipping groups with no rows meeting the group criteria.
If you were able to, in your data source, have a count of total # of credits for each group, then you could use the 'print when expression' property on the static text. e.g:
new Boolean ($F{total_credits}.equals(0));
The static text would need to go in the group header or footer as it wouldn't work in the group detail section (it would print out multiple times).
You may need to create a variable instead of use $F{total_credits} directly - I'm not certain how JasperReports deals with accessing fields in group footers. You may also find that in the group header it picks up the correct total_credits while in the group footer it doesn't.
The other way would be to have a variable that counts the total # of credits in the group. You would need to set the 'reset type' for the variable to 'group', then set the reset group. The Variable expression would be something like:
$V{myvariable} +
($F{credit_or_debit}.equals("credit") ? new Integer(1) : new Integer(0))
and the initial value expression would be new Integer(0)
Then in the group footer you could use the 'print when expression' on the static text to look at the variable.

I need to create a field to put on group footer #1 that shows the latest price by customer type. The grouping is item_ID (see below). So for example if there were transactions over time with varying prices to Factories and to Retail stores, it would only show the price for the last time that item was sold for a factory(I have a separate field for retail stores). I have tried a few things but nothing is working. For example:
On the detail level:
if {TRANSACTIONS.TRANDATE} = Maximum ({#FactoryTranDate}, {TRANSACTION_LINES.ITEM_ID}) then
{TRANSACTIONS_LINES.PRICE}
FactoryTranDate is basically: if customer type = factory then trandate. Then I created a max of this on group footer #1.
This appears correctly on the transaction line but if the last transaction for that item wasn't to a factory, it will be 0 on the summary line. I tried to do a Max of that detail level field but it doesn't come up for my summary fields, I am assuming cause it gets confused upon doing a summary of a summary?
Sounds like the problem you are running into is the column of data you are trying to print in the footer has multiple rows and you can't predict where the value you want might be within those rows. So by the time you get to the footer, it only has the value held by the last row that printed.
To get around this you would want to use a few formula fields to create variables that can be used to store the value you want from the correct row when it is printed.
I would plan to use 3 formula fields. One to initialize your variable and set it to a default value of zero. Place this formula field in the header that corresponds to your footer and this will ensure the variable exists and is reset to a default value for each grouped value in this header. The formula will look something like this:
WhilePrintingRecords;
Shared NumberVar price:=0.00;
The second formula will declare the same variable again, and it will also include some logic to know when to set the value of the variable. This formula field should be placed within the section that prints the detail records for the grouping. The formula would look something like this:
WhilePrintingRecords;
If <condition to evaluate> Then
Shared NumberVar price:={TRANSACTIONS_LINES.PRICE}
I'm not entirely sure what condition you will want to evaluate here though based on the information you've provided, but I suspect it will be along the lines of if customer type = factory. However, it should be a condition that is only true when you want to capture the price of the detail record within the grouping. If you have multiple cases where it might be true, then you will want to sort them in such a way that the one you wish to capture is printed last within the group. Since you stated that it should be the last factory price, then I would sort by Transaction Date and the variable will change its value with each record that has a true condition and will only keep the price from the one with the latest Transaction Date.
The third formula field is simply for printing the value of your variable in the footer. This field will be placed in the footer section and will display the value of the variable on your report. The formula for this field will look something like this:
WhilePrintingRecords;
Shared NumberVar price;
The formula fields used in the header and details sections can be suppressed if you don't want them to print on your report, but I would recommend waiting until you have the final value printed in the footer verified before suppressing them. This will allow you to see how the value of your variable changes as the report is generated if you are not familiar already with using variable in this manner. You may also want to read up on the scope of variables in crystal reports if this is a new topic for you. My suggestions here all use the SHARED scope, but there are also LOCAL and GLOBAL scopes. GLOBAL might work better in your case, but I tend to favor SHARED in examples such as these because they have the most broad scope. LOCAL definitely will not work for you here though.
If a row has the same ID as the last one, I want to combine them - summing up the cubicFt and Savings. $perFt divides the savings by the cubicFt, so it wouldn't be summed, simply dividing the new results. I also want the Descriptions to be concatenated, like this:
Make a Group based on ID (or whatever the leftmost column is). Then suppress the Details section and the Group Header. Instead, you'll be putting all the fields you want to display in the Group Footer. From there it's simple:
Create a Summary or Running Total for both cubicFt and Savings.
Reconfigure your $PerFt to use the summary/running total fields you made in step 1.
Combine the Descriptions by creating a shared string variable Descriptions. Whenever the group changes, reset it with Descriptions = "". Whenever the group doesn't change, add the description string to your variable. Something like:
Descriptions = Descriptions & " ; " & {yourtable.Description}
Then create a final formula ShowDescription in the Group Footer to display the results with RIGHT(Descriptions, LEN(Descriptions)-2)
You need to do grouping, either by modifying the SELECT statement or the stored query that generates the data, or within Crystal Reports. I'm literally 20 years out of date on Crystal Reports, although I have used similar software, so this will have to be tweaked.
For the first solution, all you need is a concatenation aggregation function for the string field. Your DB may or may not have one built in, so you may need to add it.
SELECT Building, ID,
SUM(cubicFt), SUM(savings),
SUM(savings)/SUM(cubicFt) AS [$perft],
LEFT(STRING_AGG(description, ';'), -1) -- drop extra ; at end
GROUP BY Building, ID;
However, you should be able to do the same within Crystal by setting this up as a subtotal group (not sure if you have to do user definitions for the string aggregation), and then hiding the detail section.
I have a series of transactions that contain a receive and return date and are grouped. In the group footer, I want to print the receive date of the first record in the group and the return date of the last record in the group. I created a formula to populate only when it is the first record in the group. But if the group contains more than one record, the formula field prints out blank. If there is only one record in the group, it prints OK. I'm using SAP Business Object Crystal Reports 2013.
There are a few ways to handle this. If you were sorting by Date, (which I've just learned you aren't) you could use a Summary to find the Minimum value. You'd place it in the relevant Group Footer and it should reset each time.
But since you're not sorting them by Date, I'd try setting up a Running Total that counts the number of records in the current Group (and resets on change of group.) Then set up a Shared Variable in a Formula that gets set every time the Group Count resets to 1. Finally, put another Formula in the Group Footer which prints out the Shared Variable.
Done correctly each Group Footer will display the first date value in that Group.
how to reset crystal reports variable value to 0 again for different group, or if I can make a variable that work only on one group but different value for another group? thanks
Create one shared variable for each group. At corresponding group header, reset the value of shared variable to zero. Below is what you can write in group header formula.
Shared numbervar num:=0;
I hope this helps.

check this it will be helpful
As we know, field “record number” from “special fields” in Crystal Report starts from 1 and increase one by one for each record until last page of the report. However, when we need a record number field that resets from 1 whenever the group field changes, we need to manually create it.To create the record number field, here are the steps:
Create a new “Running Total Field”
Give a name for the field, for example : rtf_recordNumber
Choose a field to summarize.
Set the “Type of summary” to “count”
On “Evaluate”, choose “For each record”
On “Reset”, choose “On change of group”.
Choose the “key” group name field that will reset the record number.
Click OK
Add the field to the report.
this instructions are from above link
I agree with the above answer but only small correction instead of group footer place the reset formula in group header.
I need to design a report that has some very specific requirements that I am having problems with.
The report needs to have fixed margins at the top and bottom (to allow for pre-printed content on paper). In the body of the report, there needs to be two seperate columns of data (student information). Below this, there needs to be a section that will contain information that will wrap to a new column depending on its length (student course and grade information). In addition, the course/grade information cannot break up a given academic year. Finally, there needs to be messages indicating "(End of Column)" and "(End of Transcript)."
Also, due to the nature of the data, I currently have the different sections of the report broken into sub-reports.
What would be the best way to design this report?
You can use a Tablix to allow your data to be displayed in two columns.
For the rows in the tablix you can leave "CanGrow" as "true" to ensure that it wraps and you will need to set grouping on your datasource based upon year.
You may need to set up a new field in your database that is set to only the year, then you can create a group on that field in your report. If this is SQL Server, you can add the following to the end of the "SELECT" statement before the "FROM" statememt
,DATEPART(YEAR,DateField) AS Year
For "End of column" and "End of Transcript" you will use grouping. You can set group headers and footers to display messages as required.

Update in response to op comments:
In addition, you can use expressions in to group on for data, so you can probably group with the following expression:
=FORMAT(Parameters!YearField.Value,"yyyy")
