Does anyone know if this is possible
Many Thanx in advance

I actually also see the need to be able to have a default value on a dynamic list.
We need to write reports where the user can either:
1. Select a value from a parameter (ranges), in which case the report must filter on the parameter, or
2. Do not do any selection, in which case the report must not do any filtering. And for that I want to default the parameters to .e.g A to Z in the case of a range, or default it to "All" in the case of a straightforward selection.
I don't know if I am missing something in Crystal XI, but I do not see any other way in which I can prevent filtering if no parameters are chosen

A common solution is to use a Union All in a query to get the ...All and the dynamic values using a Command Object.
select '...All' from tableUNION ALLselect field from table

Can we set default value to dynamic parameter?

Hi, I am using BO XI and CR XI. I want to set default value for dynamic cascading parameters as 'ALL' when i open report in BO Xi INFO view.I think is not possible.can anybody know solution for this. 

Hi,
I cannot imagine why you would want to do this. The nextvalue from sequence would just the next available number from the sequence, the numbers wouldn't necessarily even be sequencial. So not very useful as a parameter to a report.

How to set a default date as a parameter in Microsoft Reporting Services 2008 to January 1st

How can I set a default parameter for date for 01/01/yyyy.

Hi Giss68,
If I understand correctly, you want to set the first day of current year as a default value of a parameter in Microsoft Reporting Services 2008 report.
If in this scenario, we can use the expression below as the default value in the parameter:
=DateAdd("d",-DatePart(DateInterval.DayOfYear,Today,0,0)+1,Today)
The following document about DateAdd function is for your reference:

How to default the value in Parameter ?

Hi all,
How am I going to default the paramenter say I have the From Item >= '0' and To Item <= '99999999', I will like system to be defaulted back the value in the parameter everytime when the refresh is being pressed ?
Currently, I have set the default value in the parameter, it work fine for the very first time, but after I have put the search value in the refresh button, the system still showing the old value which I have keyed in earlier. I want system to be defaulted the value that I keyed in the parameter. How to do that ?

Hi Lim
Are you using Discoverer Plus?
If so, there is a preference in pref.txt that controls whether the parameter values are saved with the workbook. It is called SaveLastUsedParamValue. This has two settings as follows:
0 - Use the default value as set by the report writer
1 - Save the value the user just entered and use that as the default the next time

Setting reports default path

Hi buddies...Can we call our reports from a default location specified by us as we call the forms from a default location set in "default.env" file throuh parameter:

Hi!
Cause i don't use oc4j at all and my forms/reports run via IAS at a network share, i am not sure.
In your %dev_home%/reports/conf folder exists the config file rep_your_pcname.conf.
Look for:

How to set the default selection to "Select All" in a Multi valued parameter in SSRS 2008?

Hello Everyone,
How to set the default selection to "Select All" in a Multi valued parameter in SSRS 2008?

You need to specify "Default Values" in the report parameter property. Choose similar option used in the "Available Values" option, this will allow the parameter to check "Select All".

Dynamic parameter default values

Hello guy,
i'm having a little problem, i hope someone in here can help me. So, here is my situation:
I'm building a windows forms application in C# to display some reports. As i want to redesign all the controls, i made my own prompt to fill in the parameters. This works really fine, except one thing:
Whenever a parameter has default-values (so just a list of values is allowed), I switch from a textbox to a dropdown-menu filled with the default values.
No problems with static parameters, but i can't find a way to access the default values from dynamic parameters (values are retrieved from SQL-Server). The default prompt from the report-viewer can do it right, so i hope you can hep me with my following question:
Is there a way to obtain these values? Or at least the SQL-statement that is used to get them?
thanks
using:
Visual Studio 2010 v10.0.30319.1
Crystal Reports runtime engine .NET 4, v13.0.1.220
Crystal Reports for Visual Studio v13.0.1.220

I don't think the CR or Enterprise .NET SDK has any public APIs to retrieve default dynamic prompt values for crystal report parameter. With Java SDK there are no direct methods as well, however you can tap the HttpResponse object to read the prompt values that are sent to your viewer by the server as the viewer displays them and prompts you to select parameter value, however this method is not officially supported. With .NET SDK I am not sure if it is even possible. You have to use the standard viewer to see those values and let the viewer prompt with them, ratherthan your own controls.
Hope that helps.

How can I set the date today as default value in a parameter?

Hi,
I have in my report a date parameter and I want to set as default value the date today.
How can I do this?
Thanks in advance

If you are using a datatemplate , you can have a beforereport trigger that will have a package call.
In the package spec, define a date variable and also define the function beforereporttrigger that retruns boolean.
In the body, define the beforereporttrigger function with
begin
select sysdate into specvariable from dual
return(true);
end;
You can then use the variable in the datatemplate as :variable.
Hope this helps.

How to set Default value of a parameter to display Current Date

I need to display the Default value for my parameter 'As of Date' which is of datatype Date as Current Date[DD-MON-YYYY].
How can I do This??

As Tamir-L pointed out, there is no direct way to do this, but there is a workaround:
First, create a new parameter, but do not base it on any item. Give the parameter a default value of "Today".
Then, create a condition like:
 ( :myParam = 'Today'
 AND <date_item> = sysdate)
OR ( <date_item> = to_date(:myParam, 'DD-MON-YYYY'))Where :myParam is the parameter you created, and <date_item> is the item you are comparing against.
To make things a bit more bulletproof, you could create a calculation that returns sysdate when the parameter is 'Today', a date when the to_date is successful, and NULL when the to_date fails, and use the calculation in the condition.

Dynamic parameter against table TVTWT

I currently have the table TVTWT linked in order to get the name description for the distribution channel.
For example, distribution channel 00 has two rows, one german and one english.
In my dynamic parameter for distribution channel, when I try to show the name description of the distribution channel in the drop down, I get only the german name description instead of the english description. When I look at the connection for the datasource, the language is set to EN. Is there anyway I can get around this issue?
thanks for any assistance.

Please re-post if this is still an issue to the Data Connectivity - Crystal Reports Forum or purchase a case and have a dedicated support engineer work with you directly

Can I modify the data type of a dynamic parameter?

I am using CR2008 against an Oracle 11 db and have a report with dynamic parameters.
One of the report sources is a custom view that selects all of the possible 'pay ending dates' where one of the fields from this view is used as the source for the dynamic parameter.
The view performs a TRUNC on the date field in an effort to eliminate the TIME component.
The problem is that the parameter definintion defaults to DATE/TIME (vs. just DATE). I'm wondering if there is any way to modify the data type of the parameter to be DATE only.
I've searched several forumns but have not found anything.
One solution I can think of is to have the custom view format the date field as a VARCHAR (sans the time component) which I assume would force the dynamic parameter data type to string, and then have the report perform a todate function on the value when applying the criteria.
Anyone else have an idea? Just seems like CR should allow the developer to specify the data type- especially b/w Date and Date/Time, rather than make an assumption.
Thank you in advance-
emaher

emaher,
Here's what you can do:
Leave the existing date column as it is in the view...
Just add another column to the view that casts the the date as a VarChar data type and formats the date as you would like it to be.
So now you'll have 2 date columns in the view... 1 that's still a date and another that a character string.
Now for your parameter, use the date version as the parameter value and the text version as the parameter description.
Be sure to set the "Prompt with description only" is set to true.
This way the user sees the LoV in the desired format but there's not need to wrangle it back into a date for data selection.
HTH,
Jason

Problem using default value of report parameter 1 to validate parameter 2 passed in to report

I am having a problem with an SSRS report using the default value of report parameter 1 to validate parameter 2 passed in to report (via C#) instead of using the value of parameter 1 that is also passed into the report. Here are the
simplified details:
Using SSDT, SQL Server 2008 R2
SSRS report has 2 parameters:
P1 -- text, hidden, default value 'R1', ... front-end C# code can pass 'R2' or 'R1'
P2 -- text, allows multiple values, list of available values provided by stored procedure (sproc_list) that takes P1 value as a parameter. Hence, sproc_list either provides a list for P1 = 'R1' or P1 = 'R2'.
List for P1 = 'R1' is 'A', 'B', 'C'
List for P1 = 'R2' is 'A', 'B', 'D'
Values for P1 and P2 can be passed in via C# to the report.
The C# front-end displays 2 report choices to the user, R1 and R2, where both choices call the same RDL; but choice R1 passes in 'R1' for P1, and the choice R2 passes in 'R2' for P1.
Upon a users 1st time use of the report no parameters are passed in. Then when the user exits the report, the parameter value for P2 that was chosen is saved off to a file for R1 or R2, and used the next time the user selects the report.
Everything always works fine for report R1 since the default value for P1 is 'R1'.
When R2 is chosen and the user selects 'D' as the value for P2, runs the report, then exits, the P2 value of 'D' for R2 is saved to a file. When the user returns the next day to run report R2, 'R2' is passed for P1, and 'D' is passed for P2.
This is when the problem occurs. The value of 'D' for P2 is validated against a list generated for P2 based on the default value of 'R1' for parameter P1. Hence, SSRS considers 'D' an invalid value for P2 and blanks out the P2 parameter.
The user can then use the drop down list for P2 and choose 'D', but this defeats the purpose of saving the parameter values to be used the next time.
Why is the stored procedure that provides a list of available values for parameter P2 using the default value of 'R1' for parameter P1 instead of using the value of 'R2' passed into the report for parameter P1?

Hi Tom,
Sorry for my delay.
If I understand correctly, you have two parameter in your report. It is a couple of cascading parameter. If we have choose ‘R1’ of P1, the P2 values is A, B, C. ‘R2’ of P1, corresponding P2 values is A, B, D. What your requirement is to save the end use
select option of these two parameters.
In SSRS, if we have configure the parameter with default value. When we run the report, the parameter will fill with the default value to filter data. If we want to save the last status we are render the report, we need to update the default value of P1.
If we are query the default value from database, if possible, we can
update the database try to resolve the issue. Alternatively, we can set the dynamic default value for the parameter.
Hope this helps.

User defined function to set a default value of a column

Hi All
Can we use user defined function to set a default value of a column ??
for example:
create or replace function test1 return number is
begin
return 10;
end;
create table testt
(id as test1,
name varchar2(20));
error:
ORA-02000: missing ( keywordThanks

ORA-04044: procedure, function, package, or type is not allowed hereUsing PL/SQL code like that raises 2 basic problems. If that PL/SQL code for the calculating the column default breaks, what happens to the SQL insert statements against that table. These will need to fail as the table definition depends on the PL/SQL code. This is problematic as this dependency simply increases the complexity of the SQL object.
The 2nd issue is performance. PL/SQL code needs to be executed by the PL/SQL engine. This means a context switch from the SQL engine to the PL/SQL engine in order to determine the default value for that column. Context switching is a performance overhead.
So even if it was possible to use a PL/SQL function as parameter for the SQL default clause, I would not be that keen to use it.
