Using Variables in a "Report Custom Functions"

Hi!
I created a custom function using Basic Syntax where I am trying to declare/use variables. I keep getting syntax errors and don't know why. Here is my code so far:
Function cdQSIPeriod () As String
YY = Year(CurrentDate)
MM = Month(CurrentDate)
If MM = 1 then
    MM = 12
    YY = YY - 1
else
    MM = MM - 1
cdQSIPeriod = String(MM)& String(YY)
End Function
Any help you can provide will be appreciated.

You need to add
dim YY as number
dim MM as number
HTH,
Carl

Access Report Custom Functions from code

Post Author: leedo
CA Forum: .NET
Hello,
I am using VS2005 (VB) and was able to change formula text from within code using the "FormulaFieldDefinitions" object. However, I am having problems finding out how I can do the same to Report Custom Functions. The reason I am doing all this is that I noticed during my Windows app is running the source of my .rpt file is thrown in the user "Local Settings\Temp" folder and all code is revealed by simply opening that file. Please help. ThanksLeedo

It looks like it is not possible to access the custom functions within a report using the CR .NET SDK. However, to address the potential security issue that you may be concerned about, is this a Windows or ASP.NET application? If this is an ASP.NET application, then you shouldn't have to worry about the security as the end-user (client) will not be able to access that folder since the rest of the web server is typically unaccessible by the client.
Another way to secure your reports is to use what we call "managed reporting" solutions such as Crystal Report Server or Business Objects Enterprise, which manages reports securely and your users are only allowed to access/see what you allow them to. These solutions also provide public SDKs so you could incorporate the system into your own applications. For more information, go to www.businessobjects.com/products.

Using variable coulmn name in sql function

Hi there,
I am not an expert with PL/SQL and I can not figure out how to use variable column names in my function.
My function is:
CREATE OR REPLACE FUNCTION RESET_TRIGGERS(aTrigger VARCHAR2) RETURN NUMBER IS
TEMP_ID NUMBER;
TEMP_USER_ID NUMBER;
BEGIN
SELECT 'LIMS.'||'$aTrigger'||'.NEXTVAL' INTO TEMP_ID FROM DUAL;
SELECT 'LIMS.'||'$aTrigger'||'_USER.NEXTVAL' INTO TEMP_USER_ID FROM DUAL;
IF TEMP_ID > TEMP_USER_ID THEN
LOOP
SELECT LIMS.SQ_U_FINALRESULT_USER.NEXTVAL INTO TEMP_USER_ID FROM DUAL;
EXIT WHEN TEMP_USER_ID = TEMP_ID;
END LOOP;
ELSE
WHILE TEMP_ID < TEMP_USER_ID LOOP
SELECT LIMS.SQ_U_FINALRESULT.NEXTVAL INTO TEMP_ID FROM DUAL;
END LOOP;
END IF;
COMMIT;
RETURN (TEMP_ID);
END;
What I want is that I pass a seqencename with aTrigger and that two triggers will be equal if not.
eg ifaTrigger = 'SQ_U_FINALRESULT'
than I want the triggers LIMS.SQ_U_FINALRESULT and LIMS.SQ_U_FINALRESULT_USER to be set equal.
The above function will not work, but what will?????
I hope you can help me out!
Cheers

A very strange function indeed.
But here is what I think he meant to do:

9 procedure reset_sequence_value
10 ( p_sequence_name in varchar2
11 , p_current_value in number
12 , p_new_value in number
13 )
14 is
15 l_dummy number;
16 begin
17 execute immediate 'alter sequence ' || p_sequence_name || ' increment by ' || to_char(p_new_value-p_current_value);
18 execute immediate 'select ' || p_sequence_name || '.nextval from dual' into l_dummy;
19 execute immediate 'alter sequence ' || p_sequence_name || ' increment by 1';

21 ;
22 begin
23 execute immediate
24 'select ' || p_sequence_name || '.nextval,' || p_sequence_name || '_user.nextval from dual'
25 into l_nextval1, l_nextval2
26 ;
27 if l_nextval1 < l_nextval2
28 then
29 reset_sequence_value(p_sequence_name,l_nextval1,l_nextval2);
30 end if
31 ;
32 if l_nextval1 > l_nextval2
33 then
34 reset_sequence_value(p_sequence_name || '_user',l_nextval2,l_nextval1);
35 end if
36 ;

Query Stripping not working properly when using variable in the report

We have issue with WEBI document that have query stripping enable.
Once the query stripping enabled there is no data return in the report.
We have investigate on the problem, the query stripping function are notable to retrieve objects that indirectly used in the report
as we have
many variable in the reports.
Ex.
Var1 = object1 + object2
Var2 = Object3 + Object4
Var3 = Var1 + Var2
Var4 = Object1 + Object2 + Object3 + Object4
If we use only Var3 in the report, the object1,2,3,and 4 will not be
retrieve.
But if we are using Var4 in the report, the object1,2,3,and 4 will be
retrieve properly.
Please let me know is it a by-design behavior, if yes please share points on it

Hi Amit,
Thank you for response, however i already had alook on that VIdeo and it tells us about the basic enabling of query stripping.
But my question is when we have a Variable in a report which is dependent on the other two variables it gives me #error so is it by design or not.

Abhinav

Trouble migrating Crystal Reports Custom Functions from BOXI R2 to BOXI 3.1

I can't seem to migrate the custom functions from the custom function repository in my R2 environment to the 3.1 with FP 1.3 environment.
When I migrate Crystal Reports using the Import Wizard, they all come over and they retain their custom functions, however, they don't bring over or create a new custom function repository.
When I do run the import wizard I have selected the repository radio button, but it does not have any affect .
How can I migrate all of these custom functions without having to manually open up reports and placing them back into the repository on the new server?
Thanks,
Randy

Hi,
so if they are published to Rel.2 this looks different.
Just to clarify it a bit more...these Files are no Datasources for Reports and Universes and your Users dont consume them via InfoView?!
Whats the purpose for these Files? If they have none, you can de- select them in the UMT and dont migrate them (or better said move them cause you wont actually migrate .csv files). But if nobody touches them, you can move them with the UMT during daily business...how long it will take i cant estimate it. But 65GB for .CSV files is a huge amount.
But you are correct, to move them from Rel.2 to BI4 you have to use the UMT.
If you have the ressources and time i would recommend the following (Thats what i usually do with my customers):
1. Setup a Machine (could be a VM) with the same OS and BOE Version (included SPs and FPs) as your production Rel.2
2. Schedule a half day or day Downtime to copy the content 1:1 from the production Rel.2 to the VM Rel.2 with the IW or CMS DB Copy. Or do this after Business Hours.
- With this Size of your FileStore i would recommend the CMS DB copy way.
- Now you have a 1:1 Testing Environment of your Production Environment
3. Use the UMT to migrate from your VM Rel.2 to your BI4 installation
- Here you can see how long it takes
- You can check if the UMT is capable for this 65GB transfer
- Can sort out other possible issues
- Do some other Testing
After you did that you have a perfect estimation on how long the Migration will take and what for issues you are facing. With this information you can decide if you need a downtime or can do it after Business Hours f.e.

Use CustomFunctionController to add Repository Custom Function to a reportclientdocument

I would love to know how to add a Repository Custom Function to a reportclientdocument - If this is possible? I need to know how to instantiate an object of type Custom Function from the enterprise repository or get a list of available custom functions. The following code takes a "custom function object" from an existing report (which is a repository custom function) and I THINK adds it to the reportclientdocument - in fact the count of items in the customfunctioncontroller is 1 after I add the custom function but when I save the reportclientdocument they dissapear - I am not sure if I should be using ADD or INSERT method. I also was able use other controllers such as the DataDefController which works sucessfully. Please can someone help me figure out how to do this (btw where in CI_INFOOBJECTS is a custom function stored?) Thanks Nicole Dim rptClientDoc As ReportClientDocument 'open the report rptClientDoc = OpenReport("report1", ceInfoStore) Dim myCustomfunctions2 As CrystalDecisions.ReportAppServer.DataDefModel.CustomFunctions Dim myCustomcontroller2 As CrystalDecisions.ReportAppServer.Controllers.CustomFunctionController myCustomcontroller2 = rptClientDoc.CustomFunctionController() myCustomfunctions2 = myCustomcontroller2.GetCustomFunctions() Dim cf As CustomFunction cf = getfunction(ceInfoStore, ceSession) ' Gets valid custom function object in ANOTHER report myCustomfunctions2.Add(cf) Dim datacont As CrystalDecisions.ReportAppServer.Controllers.DataDefController datacont = rptClientDoc.DataDefController datacont.RecordFilterController.SetFormulaText("currentdate > month(testing)") SaveNewReport(ceInfoStore, rptClientDoc, "report1", "report2")

Report custom function and repository custom function

Hi Guru:
We have some repository functions.
When using them in the report, in design time, we will choose Add to report for the functions and then we could use it.
Then the repository functions are updated, and I found the report function, which comes from the repository function, is not updated, I need to add the repository function to the report again to update it.
As we will have more and more reports using the repository function, in the long run, is there a way to automatically update the report function from the repository for all the reports?
Thanks.
Eric

From Crystal's online help:
Repository objects that are used in a report and are connected to that report's repository can be updated automatically when opening the report in Crystal Reports. This behavior is controlled by an Options setting and is global for all reports.
Note: Objects that are used in a report but are disconnected from the repository are not automatically updated when the report is opened.
To set the update option
On the File menu, click Options.
The Options dialog box appears.
Click the Reporting tab.
Select the Update Connected Repository Objects on Open check box.
Click OK.
If you don't want to use this global option, you can also update a report's repository objects by selecting the Update Repository Objects option on the Open dialog box for an individual report.
Note: When you open a report that contains a command that is stored in the repository, and you have specified that you want to Update Connected Repository Objects on Open, only the definition of the command is automatically refreshed; the data that the command returns is not updated until you click the Refresh button in the report.

Use variable in user report ...

hi all, once i create the query with variabel [%0] and [%1] and then i create the user report on saved query form. In report designer i want to display the value of [%0] and [%1] on the report on data field how can i do that ? and what is the use of textbox variabel number and edi box variable on datafilend properties. Thanks

It is my understanding that you cannot print the user input variables in a report. I believe that will be available in a future version, probably 2004.

Use variables to create a custom Closed Captioning option

Hey,
I have a click box and text caption. On click of the click box I want to display a text caption and then on all slides throughout a project want that text caption box to remain on each screen, but want the content in that box to change per screen.
What's the best way to do this?

It is possible to do this but it's a bit involved because it requires that you run a check ON Slide Enter of each slide to find out if the CC captions should be displayed. And since those captions will be different objects on each slide, you'll need to set up a different Conditional Advanced Action for each slide. That's a lot of work just to replicate something that Captivate can do with its own CC text feature.
Here's one way to do it:
You place text captions that share the same style and size on each slide. Each caption should have the appropriate CC text for the audio on that slide.
Set up a variable to track whether the user has clicked the button to activate CC text, then set an Advanced Action to show the text caption on the slide where the user clicks this button.
For all the other slides, you need a separate Conditional Advanced Action to be executed ON Slide Enter to check the value of this CC variable and then SHOW the CC text caption if the variable is set to TRUE.
If you don't have too many slides in your project then this might be OK. But if you have a longish project with dozens of slides, you're going to get to hate this pretty quick.

SIT on SSHR using custom function

Dear Group,
I am implementing SSHR for a customer, the customer needs to have some special request that need to be entered from SSHR then follow an approval path.
So I have created a SIT and copy the original process using workflow and create a custom function in SSHR with different parameter for process and pCalledfrom.
My problem is that the with I try to display my segment only it’s not getting displayed
For example:
SIT: XX_Ticket_Request
Segments:
No_Ticket_Request
Ticket_Type
In the personalization:
In the segment field I wrote:
XX_Ticket_Request|SEGMENT1| SEGMENT2| SEGMENT3|
Nothing is displayed only start date and new date if I try to insert a new line the required segment are displayed.
How I can display the required fields only. before insert mode.

You need to use the name of the flex segments, not the columns, e.g.,:
XX_Ticket_Request|No_Ticket_Request|Ticket_Type|
Let us know if that works!

Custom Function

I am trying to create a custom function to include in the Functions, and under the Custom Function I want to have the currency format: "cdCurrencyScalerChoice" which I found in the Crystal Report sample: "Order PRocessing Efficiency"
Jack..

I use CR XI, so this answer is based on that version.
Select a formula and edit.
Now that you are in the formula workshop, you should see "Report custom Functions" near the top of the list.
You should be able to select, and copy the custom function ( be sure to note, if this is Visual Basic, or not )

How to use customer exit variable in the report

Dear All,
i want to use a standard customer exit variable in the report properties.
In the Bex Query Designer right hand bottom you will find two buttons "Properties" and "Task". Click on task you will get different option. Choose properties from there and then select "variable sequence tab".
I need to add a standard variable there. How can i achieve it?
Appreciate your early help.

You need to add variable to corresponding charctertic then you can get that varaible for sorting the sequence....
If 0CUST is the varaible then you need to assign it 0CUSTOMER then 0CUST will be available for the sequence.

How do you identify all reports using a specific custom function?

Is there a way to identify all Crystal reports that use a specific custom function? When we make changes to the function we need to re-attach the function to the existing reports, but we need to know what and where they are.
We are using CRS XI.
Thanks.

How to use a variable value set from custom dll in dataset

Hi,
I've inherited a SSRS report that I need to add some functionality to. I'm setting a variable, ADAuthorizations, from a custom dll
ADAuthorizations is a string of all AD groups a user is a member of and I need to use this as a filter in a dataset. I've tried using this variable as shown in the query below but I'm getting an error "The expression used for the parameter 'Unit_Permissions"
in the dataset "Unit_Permissions" includes a variable reference. Variable values cannot be used in query parameter expressions." Is there another way I should go about doing this?
= "SELECT UnitCode, UnitName " &
"FROM dbo.VW_Unit_Permissions " &
"WHERE UserId in (" & Variables!ADAuthorizations.Value & ")" &
"ORDER BY UnitName "
Thanks,
Robert

Please follow below steps,
1. Create a custom code to get all the users in an array,
Public Function getUserName() As String()
   dim Users(1) as string
   Users(0) = "user1"
   Users(1) = "user2"
return Users
End Function
2. Create dataset using the below query,
SELECT UnitCode, UnitName FROM dbo.VW_Unit_Permissions ORDER BY UnitName
3. Add a parameter @User and set properties : (Datatype as text, Allow multiple values, Visible)
Under "Available Values" select specify values and set the label and values as expression.
=Code.getUserName()
4. Similarly for "Default values" as
=Code.getUserName()
5. Go to tablix properties and select the filter tab and set the properties as below,
- Select Expression "UserId" i.e =Fields!UserId.Value
- Operator as "IN"
- Value as =Parameters!User.Value
6. Preview the report.
