Dynamic Parameter Error......

Crystal Reports 2008
Version 12.0.0.683
Database: MS SQL Server 2005
Connection: OLE DB
Simple Crystal Report file based on one table.
Table has 10 records and 3 fields/A, B, C/.
Parameter based on field C.
Parameter has been set up as "dynamic".
If we do something/ update, insert, delete/ with the table records , then list of values in the parameter changes automatically and shows current table records in the prompt list of values.
Report works locally fine- with no problems.
When trying to save it to the Business Objects Enterprise there is an error:
"Failed to read data from the report file c:\......report path.......rpt. Reason: Failed to read parameter object"
If we change our parameter to have "static" List of Values - everything goes fine, we are able to u201Csave asu201D in BO Enterprise and
run it. But our users demand u201Cdynamicu201D u2013 not hardcoded List Of Values in the parameter selection list.
What would be the solution?
What other way, can you propose, to show changes occurred in the table when report runs in the parameter prompt list.
To change report be based on Business view is not the solution for us.
Please, let us know.
Thanks

Hello Bratyxa,
I recommend to post this query to the [Crystal Reports Design|SAP Crystal Reports; forum.
This forum is dedicated to topics related to the creation and design of Crystal Report documents. This includes topics such as database connectivity, parameters and parameter prompting, report formulas, record selection formulas, charting, sorting, grouping, totaling, printing, and exporting but also installation and registering.
It is monitored by qualified technicians and you will get a faster response there.
Also, all Crystal Reports Design queries remain in one place and thus can be easily searched in one place.
Best regards,
Falk

Thanks a lot.

Dear Thanga Raj K,
From your solution i can get my expected result, only within your solution you miss out the @ in line 32 for ToDate variable.
After i have added it, it working perfectly.
Thanks once again.

Error when uploading a crystal report with dynamic parameter into Infoview

Hi All,
I was trying to upload a crystal report which has a dynamic parameter into a Infoview. It shows an error message that say:- "Failed to read data from report file C:\WINDOWS\TEMP\tmp27A.rpt. Reason: Failed to read parameter object ". Can anybody help me in solving this?
Thanks!

CR2011 Dynamic Parameter does not show list at all

I am upgrading some Crystal Reports from CR 8.5 to 2011. Some would be better served by using a dynamic parameter to allow the user to select the data for the parameter from the database information. I have created a dynamic parameter on the Customer ID and set the description to be the customer name. I have set it to handle multiple values.
When I preview the report in the Crystal designer, I get a text box to type in but not a drop down. To be clear, I am not talking about the LOV 1000 limit here. There are only 50 customers in the sample file I am working with. I tried turning the static parameter into a dynamic one, I deleted the original parameter and created a new one.
In case it matters, the parameter is only used as part of the selection formula and if I enter a proper customer id, it will retrieve the data. This report has about 7 tables (no stored procedures or views) and a subreport of two tables that is linked to the main report on the customer id. The parameter is only used on the main report for record selection. The SQL statement in the main report and subreport did need to be reset when I first opened the report in CR2011 but I did that on both. I have verified the database and the option to verify on first refresh is checked. The original parameter did have an imported list of about 3000 customer names. I tried exporting the CR template to a new file and while the file size changed, the behaviour did not.
When I create a brand new report on two of the tables, including the same customer table, and create the parameter the same way, it shows me the list properly in a dropdown at the prompt stage.
I am not sure where to go here or what else to try. If anyone has any suggestions, I appreciate the help. TIA, rasinc

Thank for the reply Dell,
I see the logic in adding the extra table and keeping it unlinked and I do know the crazy data that can come up if I use it linked to other tables or use the fields in other parts of the programming.
However, I've now tried it several times, creating the parameter on just the name alone, with the ID alone, etc. and I still only get a text box to type into.
I have made sure the original selection criteria
{customer.Id} = {?Customer}
if from the original table, not the new one, which I assume you expected me to do.
So I decided to run the same report through CR XIR2. When I update the Set Datasource Location, I am now getting the message
"Invalid Argument provided.
Details: The alias requested 'company', contains a combination of characters which is not considered to be valid"
Company is a table containing information about the main company, not the customers. The same message pops up for another table as well.
Then I get a message that says:
"Prompting failed with the following error message: 'List of Values failure: fail to get values. [Cause of error: The table company does not exist in the document.]'
Error source: prompt.dll Error code: 0x8004380D"
This appears to be a database access issue but I know the firewalls are not a problem because I can create a new report and get the LOV properly with the same database and same desktop computer. I can take that report created in CR2011 and use it in CRXI also and get the proper LOV. Is it possible I am dealing with template corruption because there were so many items imported into the static list before?

How to hide Dynamic Parameter userid/password prompts on infoview

Hi,
I want to hide Userid/password for each dynamic parameter, which gets prompts while refreshing or scheduling a report
I do enter userid and password at CMC->database level but when report has dynamic parameter it still does prompts for each parameter.
Please advise.
Megha

I tried what you suggested..
Well I run into different error now while refreshing report suing dynamic prompt.
Error says 'List of Values failure: fail to get values.[Cause of error:Failed to the connetion.ProductName]
ProductName is my dynamic Parameter.
Please advise.

Dynamic parameter - Failed to retrieve data from the database

I'm running a report with dynamic parameters and this report ran successfully for 2 days . For no apparent reason they stopped and the error message was received. There was no interference from head office soI'm at a loss to explain why the viewer / reports suddenly stopped working.
Now I get the following message:
Prompting failed with the following error message:
'List of values failure: fail to get values. Cause of error: Failed to retrieve data from the database. Error in file UNKNOWN.RPT: Failed to retrieve data from the database.'
Error source: prompt.dll Error code: 0x8004380D
The report is running on a Oracle database using CR-Viewer XI Product version 12.01.1.r228_v20071114
I know there is a problem with dynamic parameters and citrix, but this is not run on citrix.
Please help anypne

Is this report based or Enterprise based LOV?
If you have report published to BOEnterprise, then it automatically creates a chain of objects for any dynamic parameter:
Data Connection,
Data Foundation,
Business View,
Business Element
and LOV.
Each of this objects have configurations like users rights, permissions and some have logon configuration. Failing any of those elements may cause LOV to fail.
One of the tests you may try is to test relevant Business View by connecting Crystal reports to it.
Are you familiar with Business View Manager?

Limit dynamic parameter list to data added in last month

I have a crystal reports X1 report that uses a dynamic parameter for users to select. This parameter displays all database entries for the field. The field is called PLANNAME and lists out names that users have entered from the main application screens. I want to limit the display of these plan names to the most recent based on the CREATEDATE which is a field on the table that the Planname is stored.
Is there a way that Crystal reports can restrict / limit the list of vaules returned and available for report users to select. The list is steadily growing, and now requires the report users to scroll through hundreds of plannames (that is, all the plan names that have been created over the last two years).
Look forward to any suggestions.
Regards
dave

Just a follow-up on progress ...... which has been a bit slow.
Have got into the Business View Manager and found the vaious parameter levels PLANNAME DC, PLANNAME_BE, PLANNAME_BV, PLANNAME_DF, and added the following filter to the data_foundation: (note: first part is a View I have created, )
{CRYSTALVW_EFTPLANDETAIL.PLANNAME} in LastFullMonth.
I have not been able to add the SQL expression as it errors with reference to the INCORRECT SYNTAX NEAR THE KEYWORD "select"
SELECT DISTINCT PLANNAME, DATECREATED FROM CRYSTALVW_EFTPLANDETAIL WHERE DATECREATED >= '2009-01-01'
Note, this works okat in Enterprise manager Query Analyser, but not in the DF data_foundation.
and the suggestion you made:
SELECT DISTINCT PLANNAME FROM CRYSTALVW_EFTPLANDETAIL WHERE DATECREATED >= DATEADD('m',-1,GETDATE())
This produces the same error message - INCORRECT SYNTAX NEAR THE KEYWORD "select"
and I can not get this to work in Query Analyser - error message is
Server: Msg 1023, Level 15, State 1, Line 2
Invalid parameter 1 specified for dateadd.
I shall continue to work thru this, but would appreciate any helpful hints.
many thanks

Static or Dynamic parameter

hi all,
please help me regarding this....
1)How to know whether a given parameter is a static parameter or dynamic parameter.
2)If we change dynamic parameter value using "alter system statment .." we no need to bounce the database right , that parameter change will apply to the database.
am i right???????
3)If we change static parameter value using "alter system statment .." we need to bounce the database right , than only the parameter change will apply to the database.
am i right???????????
Regards,
Vamsi.

Hi Vamsi,
1) for the parameters which can be altered by "SCOPE=BOTH" are the Dynamic parameters right,
Right
Eg:
SQL> SHO PARAMETER %PGA%
NAME TYPE VALUE
pga_aggregate_target big integer 0
SQL> ALTER SYSTEM SET PGA_AGGREGATE_TARGET=700 SCOPE=BOTH;
SQL> SHO PARAMETER %PGA%
NAME TYPE VALUE
pga_aggregate_target big integer 700
2)for the parameters which can be altered by "SCOPE=SPFILE" or "SCOPE=PFILE" are the static parameters.
yes
SQL> SHOW PARAMETER %CONTROL_FILE%
The parameters are written into the pfile as a text and the changes take affects after restarting the database.
But the SPFILE can not be change without issuing the dynamic parameter during run time of the database.There are so many parameters that can not be changed dynamically,we have to use the PFILE to make the changes.In that situation,we perform the following this to make the changes in SPFILE using PFILE.
First,open the PFILE and write the changes as a static parameter and save the changes .Now enter the following command to reflect the chnage into SPFILE :
SQL> CREATE SPFILE FROM PFILE;
NOTE: The database should be in shut mode to make changes in the SPFILE otherwise,it can occur the error message.
Hope your all doubts are clear.
Best regards,
Rafi.

Uploading reports that use dynamic parameter values

Post Author: singhal
CA Forum: Deployment
Hi,
I am having difficulty using Crystal Reports Server XI to deploy reports that were made in Crystal Reports XI.
When I create a report that uses a dynamic parameter listing, I get the follow error when I try to install it onto the server:
Failed to read data from report file C:\WINDOWS\Temp\myreport.rpt. Reason: Failed to read parameter object
But if I were to use a static parameter listing, the server will load up the report just fine. Can you please tell me what I am doing wrong and I need to do to fix the problem. As many details as possible would be helpful.
Thanks,

Does the issue happen with the built in administrator account? I believe this is a permissions issue and the permissions need to be set in business views.

Failed to read parameter object using Dynamic Parameter

Hi All
In one of my report I am using dynamic parameter, I tried to publish the report in BOXI and got the following error:
"Failed to read data from report file C:DOCUME1...LOCALS1Temp~crw{u2026u2026..-u2026.-u2026.-u2026.-u2026u2026u2026u2026}.rpt. Reason: Failed to read parameter object"
but if I change that to static parameter I am able to publish it.
I am using Crystal Report 2008 Version: 12.1.0.892
Product Type: Full
BO Version: Product: 12.1.0 © 2008 Business Objects
I went thru many forums and came up with some settings while publishing but nothing worked out. And some mentioned about the service packs and fix pack issues. But I am not sure which should be installed in order to make this work for my versions.
Can anyone please suggest, what can be done to publlish a report with dynamic parameter?
Thanks

Is there any way to add dynamic parameter in sql without breaking Server Behavior

Hello, i'm building multiple language site.. i would like to know if there is possible way to add dynamic parameter in my query, without break the server behavior.
For example:
mysql_select_db($database_dxc_conn, $dxc_conn);
$query_Recordset1 = "SELECT article.articleName, article.articleDesc FROM article";
$Recordset1 = mysql_query($query_Recordset1, $dxc_conn) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);
will become something like this:
$additionalSQL=", article.articleName_en";
mysql_select_db($database_dxc_conn, $dxc_conn);
$query_Recordset1 = "SELECT article.articleName, article.articleDesc $additionalSQL FROM article";
$Recordset1 = mysql_query($query_Recordset1, $dxc_conn) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);
this is just an example, my real scenarion is far more complicated than this... however this kind of approach break the server behavior and force to do hand-coding...
i would like to know if there's better way to do such thing like this...

Server behaviors are simply bits of boilerplate code automatically generated by Dreamweaver. Editing the code doesn't "break" it (unless your edits are badly written). However, once you edit the code, Dreamweaver no longer recognizes it, so you lose the ability to drag recordset results from the Bindings panel.
If you want to edit server behavior code, the best way to handle it is to lay out your page as you want, using the Bindings panel. Once everything has been done, only then edit the server behavior code.

How to get the list of values for a dynamic parameter using Web Services SDK?

I am struggling to get the list of values for a dynamic parameter of a report.I am using Java Web Services SDK ... I tried to use PromptInfo.getLOV().getValues() method but it does not work.First of all ... is this possible (to get the list of values for a dynamic param) using Web Services?Second of all, if this is possible, how should I do it ... it seems it works fine when running the report from CMC. It asks for DB logon info and after that it provides a list of values.Thx 

Your assumption is correct. We are trying to get the LOVs from the Crystal Report. I was not aware that this is not supported by Web Services SDK.We used Web Services SDK to integrated the Crystal Reports in our web application. We implemented some basic actions for reports: schedule, view instances, run ad-hoc reports.We encountered this problem when trying to run/schedule reports with dynamic parameters (a list of values from DB). We were unable to get the LOVs.Please let me know if you can think of an alternative to look at.Thanks a lot,Catalin

Why Dynamic Parameter is not working, when i create report using stored procedure ?

Post Author: Shashi Kant
CA Forum: General
Hi all
Why Dynamic Parameter is not working, when i create report XI using stored procedure ?
Only i shaw those parameters which i used in my stored procedure, the parameter which i create dynamic using stored procedure
is not shown to me when i referesh the report for viewing the results.
I have used the same procedure which i mention below but can not seen the last screen which is shown in this .
============================================================================================
1. Select View > Field Explorer2. Right-click on Parameter Fields and select New from the right-click menu.3. Enter u201CCustomer Nameu201D as the name for your parameter4. Under u201CList of Valuesu201D select u201CDynamicu201D5. Under the Value column, click where is says u201Cclick here to add itemu201D and select Customer Name from the drop-down list. The dialog shown now look like the one shown below in Figure 1. Click OK to return to your report design.
Dynamic Parameter Setup6. Next, select Report > Select Expert, select the Customer Name field and click OK.7. Using the drop-down list beside select u201CIs Equal Tou201D and using the drop-down list, select your parameter field (it should be the first field). 8. Click OK to return to your report design and see the parameter dialog.The parameter dialog will appear and show you a dynamic list of values that is updated each time your run your report. It couldnu2019t be easier! In our next tutorial, we will be looking at how to use this feature to create cascading parameter fields, where the values are filtered by the preceding selection.
Dynamic Parameters in Action
My question is that whether dynamic parameter is working with storedprocedure or not.
When i added one table and try to fetch records using dyanmic prameters. after that i am not be able to find the dynamic parameter option when i referesh my report.
One more thing when i try the static parameter for my report, the option i see when i referesh the screen.
Please reply soon , it's urgent

Hi Kishore,
I have tested the issue step by step by following you description, while the first issue works well in my local environment. Based on my research, this can be caused by the lookup expression or it indeed return Male value based on the logic. If you use the
expression below, it will indeed only return the Male record. So please try to double-check the record in the two datasets and the expression in your environment:
=lookup(first(Fields!ProgramID.Value,"DataSet1"),Fields!ProgramID.Value,Fields!Gender.Value,"DataSet2")
As to the second issue, please try to use the following expression:
=Count(Lookup(fields!ProgramID.value,fields!ProgramID.value,fields!Gender.value,"DataSet2"))
Besides, if this issue still exist, in order to trouble shoot this issue more efficiently, could you please post both the .rdl file with all the size properties to us by the following E-mail address? It is benefit for us to do further analysis.

How can we use C# to read dynamic parameter's value list from .rpt?

I'm using Cystal Report 2008. We know starting from CR XI we can create dynamic parameters, the list of items of this kind of parameter are fetching from database. So in general the SQLs to get the list of values for dynamic parameters are stored in the .rpt.
In Crystal Report Designer, if I preview a report with dynamic parameters, it will first query the database and then show the input dialog with list of values from database for user to choose. My question is can we implement the same thing by our C# code? I'm planning to use C# code to read this dynamic parameter's value list from .rpt and render them on the web page. Then pass back the user selected values to the .rpt to run the report after user make the choice. I didn't find any APIs can do this. Is it possible?
Thanks in advance!!

Hi,
Can you explain a bit in detail, I have similar scenario. I am using the following code but not getting the Column name for dynamic parameter list.
foreach (ParameterFieldDefinition prm
                          in reportDocument.DataDefinition.ParameterFields)
                try
                    string vParameterFieldName;
                    *vParameterFieldName = prm.ParameterFieldName.ToString();*

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
