Dynamically change parameters based on the value of another parameter? - crystal-reports

I have a crystal 2008 report that allows users to group to two levels.
I have two parameters, using which users can select which attribute they want to group on.
The two params are of type string and the list of values is static. Both levels have the same options to group on.
Is there someway to filter the list based on what they selected for param 1. So that they cannot group on the same thing twice.

I don't think it's possible. You can cascade dynamic parameters link Country, State but not how you want to.
How many options do they have to choose from? Do they normally choose anything other than a few different combinations from the maximum?
I think you're options are to either leave it as is (allowing them to pick the same thing for both groups). Or create a single parameters which looks like- Group by:
Date, Country
Type, Country
Date, Type
etc

Short answer: not possible.
Options:
create a custom UI that does what you want to do
if the list of grouping fields aren't too long, you could combine the two parameters into a single one, then list the options that you want to support. For example, if you have 3 grouping fields (A,B,C), your single, combined parameter would be A->B, B->A, B->C, C->B, A->C, C->A.

how to create multiple filters from one dimension tableau (10)?

I have a two dimensions with the following data set
Original Dimension
I would like to create two filters that can be used to filter my dashboard. These two filter would be called - "Product_Type" and "Product" and should have the following drop downs:
Filter Breakdown
To summarize, I am looking for a way to take my original dimension and create the filter breakdowns so that in my dashboard I can have two filter (Product_type and Product). When i click on the Product_type filter, i should be able to see "overall", "fruits", "vegetable" and "leafy. Based on my selection , the Product filter should automatically show only the relevant values - i.e. if i picked "leafy" it should only show "spinach" and "kale". Finally if i select "kale" my entire dashboard should change accordingly.
Looking for a way to do this without drastically affecting the performance.
update: i was able to achieve this by creating multiple parameters and then using the pop window technique (https://vimeo.com/107352893) - but this has affected my workbook performance very badly. Need another solution!!
You should be able to accomplish your desired functionality by creating a calculated field for product type and a CASE statement to classify the products based on the product type you specified your image.
Further, filters can be configured to display available values based on the other filters in place. I would recommend having your Product Type filter a the "context" or "data-source" level, and your product filter at the lowest level, so that the selectable options for the product filter can be displayed using the "only relevant Values" option and limits the products that can be chosen.
Please see the following link for some more information on filtering hierarchies

"Only relevant values - Specifies which values to show in the filter. When you select this option other filters are considered and only values that pass these filters are shown. For example, a filter on State will only show the Eastern states when a filter on Region is set. You can use the toggle at the top of the filter card to switch between this option and the All Values in Database option.
All values in database - Specifies which values to show in the filter. When you select this option all values in the database are shown regardless of the other filters on the view.
All values in context (Tableau Desktop only) - When one of the filters in the view is a context filter, select this option on a different filter to only display values that pass through the context filter. For more information, see Improve View Performance with Context Filters."

Prioritise which identifier to use

My crystal report pulls data about books, including an identifier (isbn, issn order number etc.), author, and publisher.
The ID field stores multiple ways to identify the book. The report displays any of the identifiers for that record. If one book has two identifiers; issn and order number, the report currently displays one apparently at random.
How can I make it prioritise which type to use based on a preset order? I figured some sort of filter on the field could work, but I haven't figured out how. I can't edit the table, but I can use SQL within the report.
If all the different types of ID are stored in a single field, your best bet is to use a SQL Command inside your report to separate them into multiple virtual fields.
Go to Database Fields / Database Expert, expand the connection you want to use, and pick Add Command. From here you can write a custom SQL statement to grab the information you're currently using, and at the same time separate the ID field into multiple different fields (as far as the report will be concerned, anyway. The table will stay unchanged.)
The trick is to figure out how to write your command to do the separation. We don't know what your data looks like, so you're on your own from here.
Based on the very little information that you have provided and if i was to make a guess.I suggest you make use of the formula field in your report and then use something like this to accomplish your goal.
IF ISNULL{first_priority_field_name} OR {first_priority_field_name} = '' THEN
{second_priority_field_name}
ELSE
{first_priority_field_name}
Use nested IF statement in case there are more than 2 identifier fields.

Using all input controls for use in one report

I have a report that uses a query of input controls. It is a drop-down menu of specific ID's (ie. 28, 13, 30...) I want to know if it is possible to have my report go through each of these parameters and populate the report one page at a time for each of them.
Here is an example of the different parameters I want the report to loop through:
Do you want to create a page for all Partner IDs? Or just for the Partner IDs that a user selects? Either is possible.
Using all Partner IDs is probably easier. Modify your report query which probably has something like WHERE partner_id = $P{partnerID}. Remove the where clause. Add grouping and sorting to the query to group on partner id. Each group can start on a new page. And now you don't need a parameter at all.
If you want the user to select the Partner IDs, then you need to use a multi-select input control rather than the single-select input control you're using now. Update your query to use something like this: WHERE $X{IN, partner_id, partnerID}. Add grouping and sorting as above.

Crystal Reports formula method, GroupName

I am fixing some old reports and have come across the method GroupName. I cannot find exactly what it does and am coming for support. For that matter, is there an online reference that contains a list of the built it methods in CR, parameters, etc.?
GroupName just returns a string of... well, the current Group Name. This is either just the field you were grouping on, or is a value customized via the Group Expert -> Options (Change Group Options) -> "Customize Group Name Field". It's whatever displays in the group tree.
If it's not listed in the Crystal Reports Online Help, which is oddly the case with GroupName, then your best bet is some good, old-fashioned Googling. I'm not sure of any resource other than commercial products that lists descriptions and usage instructions for all the functions, properties, etc.
EDIT: You have to pass the field you're grouping on. So, for a random example, GroupName(Patient.Patient_Type_Code) might return strings "Therapy", "Rehab", etc. from a numeric type code you're grouping on.

Create a new FileMaker layout showing unique records based on one field and a count for each

I have a table like this:
Application,Program,UsedObject
It can have data like this:
A,P1,ZZ
A,P1,BB
A,P2,CC
B,F1,KK
I'd like to create a layout to show:
Application,# of Programs
A,2
B,1
The point is to count the distinct programs.
For the life of me I can't make this work in FileMaker. I've created a summary field to count programs resetting after each group, but because it doesn't eliminate the duplicate programs I get:
A,3
B,1
Any help much appreciated.
Create a a summary field as:
cntApplicaiton = Count of Application
Do this by going into define fields, create a field called cntApplication, type summary. In the options dialogue make the summary field a count on application
Now create a new layout with a subsummary part and nobody. The subsummary should be sorted on Application. Put the Application and cntApplication fields in subsummary. If you enter browse mode and sort by Application you ought to get the data you want.
You can also create a calc field with the formula
GetSummary(cntApplication; Application)
This will allow you to use the total number of Applications with in a record
Since I also generate the data in this form, the solution I've adopted is to fill two tables in FileMaker. One provides the summary view, the other the detailed view.
I think that your problem is down to dupliate records and an inadequate key.
Create a text field called "App_Prog". In the options box set it to an auto-enter calc, unchecking the 'Do not replace...' option, and use the following calc:
Application & "_" & Program
Now create a self join to the table using App_Prog as the field on both sides, and call this 'MatchingApps'.
Now, create (if you don't alread have one) a unique serial number field, 'Counter' say, and make sure that you enter a value in each record. (Find all, click in the field, and use serial number option in'Replace Field Contents...')
Now add a new calc field - Is_Duplicate with the following calc...
If (Counter = MatchingApps::Counter; "Master Record" ; "Duplicate")
Finally, find all, click in the 'Application field, and use 'Replace Field Contents...' with a calculation to force the auto-enter calc for 'App_Prog' to come up with a value.
Where does this get you? You should now have a set of records that are marker either "Master Record" or "Duplicate". Do a find on "Master Record", and then you can perform your summary (by Application) to do a count of distinct application-program pairs.
If you have access to custom functions (you need FileMaker Pro Advanced), I'd do it like this:
Add the RemoveDuplicates function as found here (this is a recursive function that takes a list of strings and returns a list of unique values).
In the relationships graph, add another occurrence of your table and add an Application = Application relationship.
Create a calculated field in the table with the calculation looking something like this:
ValueCount(RemoveDuplicates(List(TABLE2::Program)))
You'll find that each record will contain the number of distinct programs for the given application. Showing a summary for each application should be relatively trivial from here.
I think the best way to do this is to create a separate applications table. So as you've given the data, it would have two records, one for A and one for B.
So, with the addition of an Applications table and your existing table, which I'll call Objects, create a relationship from Applications to Objects (with a table occurrence called ObjectsParent) based on the ApplicationName as the match field. Create a self join relationship between Objects and itself with both Application and Program as the match fields. I'll call one of the "table occurrences" ObjectsParent and the other ObjectsChildren. Make sure that there's a primary key field in Objects that is set to auto-enter a serial number or some other method to ensure uniqueness. I'll call this ID.
So your relationship graph has three table occurrences:
Applications::Applicaiton = ObjectsParent::Application
ObjectsParent::Application = ObjectsChildren::Application, ObjectsParent::Program = ObjectsChildren::Program
Now create a calculation field in Objects, and calculating from the context of ObjectsParent, give it the following formula:
AppCount = Count( ObjectsChildren::ID )
Create a calculation field in Applications and calculating from the context of the table occurrence you used to relate it to ObjectsParent with the following formula:
AppCount = ObjectsParent::AppCount
The count field in Objects will have the same value for every object with the same application, so it doesn't matter which one you get this data from.
If you now view the data in Applications in list view, you can place the Applications::Application and Applications::AppCount fields on the layout and you should get what you've requested.
