Summing Parameter Values ?

Post Author: Jedit
CA Forum: General
I have a sub report passing values to my main report as a shared numberVar
The sub report is in detail section A, the value returned is called linetotal & is shown in detail section B with some other values, the report works fine & I see everything I need to create the full report with a summary for the job.
This is where my issue lies!
For each job shown I canu2019t sum the linetotal parameter in my main report, How is this done????
As when I select the @linetotal field & choose insert summary there is no option to select summary?
HELP HELP
I Can post the report if needed????????

A total sum but not in the sub, I think I need to explain somewhat clearer.
I have jobs (JWO-1,JWO-2 JWO-3 etcu2026..) that have items being scrapped at different operations.
I have a main report that shows all jobs with scrap & has two sections in it, detail section A & B.
My sub report is located in section A with the following fields
JOB | OP | QTY_SCRAP | COST.
The sub report lists all lines (operations) that have been completed for a job & filters on QTY_SCRAP being >0 then sums the cost filed for all completed operations up to the operation the item/s were scrapped.
I have a shared numbervar (linetotal) that Iu2019m using to pass the summed value back to my main report.
Syntax for variable is
whileprintingrecords;shared numbervar linetotal:=Sum ({table.Cost})
Back in my main report in detail section B.
I have some other fields that describes why the item/s were found to be faulty with a cost centre, the linetotal field from the sub report appears here & I reference it up with variable linetotal in my main report as
whileprintingrecords;shared numbervar linetotal
Now, for any job my report shows items being scraped at different operations with a cost & a reason for the scrap.
I now grouped on a Job Number & try to sum all the linetotal parameter fields.
Itu2019s at this point I have the difficulty mentioned earlier?
I also want to use the values in a chart & have the same problem, the field is not available for a chart & canu2019t be summed????
I know itu2019s a bit verse & chapter but hopefully this will help?

Report based on parameter values

Morning all,
I have to create a report which includes Account Number, Account Name, Sales prices. There has to be two optional parameters, Account number (Static) and Product Description (Dynamic).
I have setup the report with Account Number (Grouped), Account Name. The report works fine, when a user selects a particular account number, the report produces fine.
Things I would like to do and know about:
1: when it comes to sales price, it should reflect to what user has selected under Product Description parameter.
for example if the user has selected Supra, Supra KNT, Rimless, Metal etc from the description parameter, the report should only show those selected prices according to the account number (showing descriptive field value).
2: Additionally, if user chooses all of the options from the drop down menu (multiple selection dexcription parameter) then the report should show all the prices according to the description (showing the description field value).
The problem in this case which I think would be is because the description values are quite alot, I mean more than 25 values and if a user selects multiple values, lets say all, how would Crystal adjust that into a report?
Example of a report
Parameters
=============
Account Number:
Description: Supra, Supra KNT, Metal, Plastic, Rimless, Rimless KNT (multiple selection)
Report Layout
============
Account Number --- Account Name --- Supra - Supra KNT - Metal - Plastic - Rimless - Rimless KNT
(Where Supra to Rimless KNT options are chosen by Descriptive parameter value - if not chosen then report will only show account number and account name).
If however only Supra is selected then the report would look like this
Report Layout
============
Account Number --- Account Name --- Supra
Any ideas how to achieve this kind of report? I have setup the report in a landscape so that we can fit as many description values as possible but I only managed to show 9, rest goes over the page.
The report in the end has to be exported to excel so I don't mind if it goes over a page.
Regards
Jehanzeb

Jehanzeb,
You do want to use cross tabs...
Have your database query produce a table with the following columns:
Account Info (Number & Name)
Product Description
Sales
e.g.,
Select AcctNo + " - " + AcctName as AcctInfo,
ProdDesc,
sum(Sales) as Sales
from SalesTable
group by AcctNo, AcctName, ProdDesc
Then use record selection to limit the data to the selected products.
Yes, the layout of a cross tab is a bit strange, in that the design of the cross tab only shows one column for the data, but the table will expand with the underlying data. If 4 products are selected, there will be 4 columns of sales numbers. When setting up the cross tab, make the AcctInfo field the row header, and the ProdDesc field the column header, and the Sales field the table cell value.

Getting QM parameter values for Raw Material on the basis of goods receipt

Hi All,
I have requirement, while generating inspection lot these tables MCXD&MCXA should update.
when we need a QM parameter value for the month, It should be the average of all the inspection lot generated for the month.
Thanks in advance
Regards
Hanamanta

Ok.. I assume your talking about the actual test result value. These do not roll up into the QM LIS structures used in transactions MCXA or MCXD.
You might be able to create your own structures and have them updated but you would have develop that.
You can create run charts for various MIC's and utilize the SPC functionality if you need monthly averages and trends.
If your batch managed you can easily get reports of batch values via the CL30N transaction. You'll want to make sure you have a characteristic for batch production or receipt date so you can sort and select by date. These can then be loaded to Excel for summing and averaging.

Why are my parameter values not setting in report?

G'day,
Like many others I am a developer who is new to crystal reports. I have researched a lot for setting report parameters and although my code seem to be working when I open the report through code I'm always asked to re-enter the parameter values.
Here is my code:
behind button event
PersonalAttendance myReport = new PersonalAttendance();
ReportUtility ru = new ReportUtility();
ru.SetReportParameter(myReport, "reportName","the title");
myReport.Refresh();
myReport.SetDataSource([a data source]);
ReportViewer.ReportSource = myReport;
method behind custom class "ReportUtility()"
public void SetReportParameter(ReportClass rc, string FieldName, object parameterValue)
//Get the collection of parameters from the report
crParameterFieldDefinitions = rc.DataDefinition.ParameterFields;
//Access the specified parameter from the collection
crParameterFieldDefinition = crParameterFieldDefinitions[FieldName];
//Get the current values from the parameter field. At this point
//there are zero values set.
crParameterValues = crParameterFieldDefinition.CurrentValues;
//Set the current values for the parameter field
crParameterDiscreteValue = new ParameterDiscreteValue();
crParameterDiscreteValue.Value = parameterValue;
//Add the first current value for the parameter field
crParameterValues.Add(crParameterDiscreteValue);
//All current parameter values must be applied for the parameter field.
crParameterFieldDefinition.ApplyCurrentValues(crParameterValues);
I'd really appreciate any assistance....

Passing Parameter values

Hi,
Iam trying to print a crystal report, but it is not prompting me to pass the parameter values.
i want user to pass parameter values.
Iam using VB.Net code to generate the reports.
Could plz help me
Thanks
Ravi

assuming v_seqprocess_id takes the process_id, I'd probably go with something like:
cursor sum_cur(p_process_id number) is
select sum(cheque_amt), sum(balance)
from table
where process_id = p_process_id;and call the cursor passing v_seqprocess_id into it.
That's if I had to do extra processing on top of getting the values, etc.
Otherwise, I'd go with:
insert into table2
select sum(cheque_amt), sum(balance)
from table
where process_id = v_seqprocess_id;Message was edited by:

TIME Dimension - TIME_SPAN parameter value (constant or decrementing?)

Hi all
For the the 'TIME_SPAN' parameter value in dimension of type 'TIME', should the value be constant for all members in a particular level or should the value decrement over time as the period progresses.
For example, for a TIME dimension having levels DAY > MONTH should the values for TIME_SPAN be:
DAY, DAY_END_DATE, DAY_TIME_SPAN, MONTH, MONTH_END_DATE, MONTH_TIME_SPAN
D01JAN2010, 01-01-2010, 1, M01_Y2010, 31-01-2010, 31
D02JAN2010, 02-01-2010, 1, M02_Y2010, 31-01-2010, 31
D03JAN2010, 03-01-2010, 1, M03_Y2010, 31-01-2010, 31
and so on...
or like below:
D01JAN2010, 01-01-2010, 1, M01_Y2010, 31-01-2010, 31
D02JAN2010, 02-01-2010, 1, M02_Y2010, 31-01-2010, 30
D03JAN2010, 03-01-2010, 1, M03_Y2010, 31-01-2010, 29
and so on...
Any assistance will be appreciated.

"Missing parameter values." -- Export and Print only...

I have a web application and I am using CrystalReportViewer. I am passing several parameters to Crystal using:
report.SetParameterValue(field.Name, Session[field.Name]);
I have session variables which will hold parameters needed to pass into the report. The session variables are populated from controls on my webpage after an onclick event. This even not only populates session, but also passes parameters to the report with the following code:
ReportDocument report = new ReportDocument();
Session["MapPathName"] = "./Reporting/CaseStudy.rpt";
report.FileName = Server.MapPath(Session["MapPathName"].ToString());
ParameterFields fields = new CrystalDecisions.Shared.ParameterFields();
fields = report.ParameterFields;
foreach (ParameterField field in fields)
report.SetParameterValue(field.Name, Session[field.Name]);
CrystalReportViewer1.ReportSource = report;
This works great for reporting and is very extensible. However, when clicking on the "Print" or "Export" buttons on the toolbar I get "Missing parameter values." I attempted to export manually in code using the .ExportToStream function but I still get the error, "Missing parameter values."
I received this error also in Refresh, Search, and Navigate functions. This was corrected by calling a function that supplies the above code block to these functions. However, I do not see any events for controlling the Print nor the Export events.
QUESTION: How can I print or export a report when passing parameters using CrystalReportViewer? Thanks in advance!
P.S. - Crystal Reports XI Release 2
Edited by: KyleSavant on Jun 18, 2009 5:42 PM

There are no Export or Print events accessible for the viewer
Since it sounds like you are creating the reportdocument object in your click event, the settings on this object become out of scope on successive postbacks executed by other events.
to get around this without major changes, you can place your "report" object in session in this event and retrieve it from session on successive postbacks. This should solve your problems around navigation, printing and exporting. What you will need to do is check if the session object exists (usually in page_load or page_initialze) and if so, retrieve it from session and bind it to the viewer's reportsource. If the session object does not exist, then do nothing (ie you have not clicked your button yet that retrieves the parameter values from session and loads the report). Also, in your click event you can check if the report session object exists and if so, remove it so that it can be re-created with your new parameter values (ie i'm assuming the only time you want to set parameter values is in this event).

Unable to get parameter values from a remote database

I am linking to a remote database view via a synonym in Oracle and trying to retrieve parameter values from it. The username and password are the same for the local and remote database and I can run the SQL query using SQL plus against the database and values are returned. However, when I try and run the same query in Crystal Reports (XI) I receive an Oracle error:
"An attempt was made to connect or log in to a remote database using a connection description that could not be found.
Action:
Specify an existing database link. Query the data dictionary to see all existing database links. See your operating system-specific Net8 documentation for valid connection descriptors. "
How can it be that Crystal cannot run the query when it is valid in SQL plus?
Any tips/info would be appreciated.
many thanks
Claire
Oracle is version 10

When running one of the reports in VS.Net this is the error I receive:
"A first chance exception of type 'System.Runtime.InteropServices.COMException' occurred in crystaldecisions.crystalreports.engine.dll

When running the same report in Crystal Reports designer I receive this error 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. Details: [Database Vendor Code: 2019].

So this one is also failing in the designer.
All the parameters in the main report are static and the ones in the subreport are passed in from the main report.

Urgent help required - linked subreport keeps asking for parameter value

Greetings,
I have developed a report in the Crystal Reports bundled with Visual Studio 2005. The data is obtained from a stored procedure. One of the fields in the result set is named "Id".
I have embedded a subreport in the details row of the main report. The subreport also gets its information from a stored procedure. This stored procedure has one parameter named "OpportunityId". This field is linked to the field named "Id" above. the subreport has been set to supress blank subreports.
In the development environment and running the executable of the application on the development machine the report works perfectly. The subreport displays as it should and all is well.
When I deploy the report onto user machines where they have the crystal runtime installed, the report keeps asking for a parameter value for the subreport.
I cannot get this to stop happening.
This report is urgently required. PLEASE could someone help me out here.
I am at my wits end.
I have attached a zipe file containing the following:
- the two stored procedure
- the rpt file
- a sample report
- a screen showing the report having just been generated
Thanks in advance,
Robert Lancaster

Hi Robert,I see your report template and stored procedures. All seems to be ok. The most important is to assign the report parameters for all linked subreports (only one in your case). Try this (in C#, in VB.NET the code are very similary): ReportDocument report = new ReportDocument(@"TopFortyReport.rpt");AssignParameters(report, paramCollection);// and now assign parameters to all linked subreports foreach( CrystalDecisions.CrystalReports.Engine.Section section in report.ReportDefinition.Sections){ foreach (CrystalDecisions.CrystalReports.Engine.ReportObject reportObject in section.ReportObjects) { if (reportObject.Kind == ReportObjectKind.SubreportObject) { SubreportObject subReport = (SubreportObject)reportObject; ReportDocument subDocument = subReport.OpenSubreport(subReport.SubreportName); AssignParameters(subDocument, paramsCollection); }} void AssignParameters(ReportDocument report, object[] paramsCollection){ int nParams = paramsCollection.Length; for (int iParamIndex = 0; iParamIndex < nParams; iParamIndex++) { if (report.DataDefinition.ParameterFields[iParamIndex].IsLinked()) continue; report.SetParameterValue(iParamIndex, paramsCollection[iParamIndex]); }}

Crystal Reports 9 and SQL Server 2005 default parameter values

We're using Crystal Reports 9 and upgraded from SQL Server 2000 to SQL Server 2005.
I'm noticing a very weird problem which I wonder if anyone else has experienced (and hopefully found a resolution for). It appears that in using Crystal with SQL Server 2005 stored procedures, if we have default parameter values in the stored procedures, the default parameter values get completely ignored if you pass in a NULL value from Crystal!
For example, if you have a stored procedure that begins like this:
ALTER Procedure [dbo].[StoredProcedure]
@Param1 VarChar(200) = '',
@Param2 VarChar(200) = ''
AS ...
both @Param1 and @Param2 have a default value of an empty string, and therefore should become empty strings if nothing (NULL values) gets passed in for them.
But, like I said, what I'm finding is that with Crystal calling the stored procedure with NULL @Param1 and @Param2 values, they never become empty strings, but rather remain as NULLs.
This was never a problem with SQL 2000.
Very perplexing. Anyone else every experience this?
Thank you.

Please ignore my earlier post -- answered my own question.
NULL parameter values do not get replaced by default values in SQL -- that is normal behavior in both SQL 2000 and SQL 2005. Just goes to show, that no many how many years programming experience you have, you can still get tripped up sometimes : (

T-sql 2012 accept null parameter values

The following t-sql 2012 works fine in sql management studio. However when I place it in a .net 2010 web form application, I am told the sql does not work when the parameter values are null. Thus can you tell me what I can change in the sql below that will
accept null as 3 possible input values?
SELECT i.[lastName]
            ,i.[firstName]
            ,i.[middleName]
            ,i.[suffix]
            ,a.[userid]
            ,a.schoolnum
            ,a.spa
            ,a.mrref
            from [OPS].[dbo].[Identity] i
            inner join [OPS].[dbo].[Person] p on i.identityID = p.currentIdentityID
            inner join [OPS].[dbo].[UserAccount] u on u.personID = p.personID
            inner join [CampusOps].[dbo].[AtnLtrUsers] a on a.userid =u.username
                   where (i.[lastName] like '%' + @lname + '%' or i.[firstName] like'%' +
@fname + '%'
                   or i.[middleName] like'%' + @mname + '%')
or (@fname is null and @lname is null and @mname is null)
      order by i.[lastName], i.[firstName], i.[middleName]"

You should create a stored procedure for this.
create procedure GetNames
(@lname varchar(max) = null, @fname varchar(max) = null, @mname varchar(max) = null)
as
begin
SELECT i.[lastName]
,i.[firstName]
,i.[middleName]
,i.[suffix]
,a.[userid]
,a.schoolnum
,a.spa
,a.mrref
from [OPS].[dbo].[Identity] i
inner join [OPS].[dbo].[Person] p on i.identityID = p.currentIdentityID
inner join [OPS].[dbo].[UserAccount] u on u.personID = p.personID
inner join [CampusOps].[dbo].[AtnLtrUsers] a on a.userid =u.username
where (i.[lastName] like '%' + @lname + '%' or @lname is null) and
(i.[firstName] like'%' + @fname + '%' or @fname is null) and
(i.[middleName] like'%' + @mname + '%' or @mname is null)
order by i.[lastName], i.[firstName], i.[middleName]
end
Also keep in mind that NULL is different than an empty string but it should work exactly like a null anyway (unless your columns/fields are also NULLable).

How to get parameter value from report in event of value-request?

Hi everyone,
The customer want to use particular F4 help on report, but some input value before press enter key are not used in event of "at selection-screen on value-request for xxx", How to get parameter value in this event?
many thanks!
Jack

You probably want to look at function module DYNP_VALUES_READ to allow you to read the values of the other screen fields during the F4 event... below is a simple demo of this - when you press F4 the value from the p_field is read and returned in the p_desc field.

Reading POST-Request-Parameter-Values from WebDynPro now possible?

Hello,
in the past I always was disappointed that in WebDynPro there was no way to read POST-request-parameter-values directly after the call of a WebDynPro-Application.
The only (documented) way to read / transfer request-data into an WebDynPro-application was via "URL query string parameters" in the request URL.
The last week I forgot this restriction. I called my WebDynPro-application using a POST-Request-Parameter (cookie_guid) instead of an URL-parameter.
After noticing my mistake, I was really surprised that the WebDynPro could read / shows the the POST-Request-Value.
I didn't make any changes in the coding of my WebDynPro-Application (zvis_show_sso_cookie).
After this cognition I built the following simple HTML-formular to analyse the behavior of the WebyDynPro by calling it with an URL-Parameter (cookie_guid=Url-GUID) together with the POST-Parameter (cookie_guid = Post-Value-GUID).
After calling the WebyDynPro it reads / shows the "POST-Value" of the request !!!
(Remark: If I made a simple refresh or type directly the URL "http://hg10762.vis-extranet.de:1080/sap/bc/webdynpro/sap/zvis_show_sso_cookie?sap-language=DE&cookie_guid=Url-GUID" in the browser, the same webdynpro reads / shows the URL-Parameter-Value).

My questions:
I there any documentation that describes the behavior of WebDynPro after calling it by using POST-Parameter values?
I believe in the past it wasn't possible to read POST-request-parameter-values in WD. Has SAP changed the functionality?
Is the behavior I described in my example above mandatory?
Regards
Steffen

As far as i know in general HTTP request GET method is standard but in SAP POST is standard. All the client request is passed as POST to the server in order to avoid the URL parameter length restriction in GET method.

Problem getting parameter values at the service end point

I am having problem getting parameter values at the service end point. I created service end point and this method is having 35 parameters and then i created test client file using Sun One Studio 5. but when i run this test client and make a call to service it sends wrong value to first three parameters to the service end point. I tried all the way round but it gave me same sort of problem. I change the order of parameters change the names of parameters but it didn�t work. And then i started chopping of parameter from the left side. And my problem is solved when my parameter list reached to 12 from 35. So is it a bug or some problem with my configuration or some thing else.
I am using sun one studio 5 with sun one app 7. My service end point does very simple thing. It only takes out put of the parameter to the server log file. And my wsdl file seems all right. There is no conflict with the count and data type of the parameter information it contains.

� I followed steps given this example. http://developers.sun.com/prodtech/javatools/jsstandard/reference/docs/s1s5/stockapp.html.
If some one know what is wrong. Is it me or some thing wrong with the method I followed. But I am sure that I followed exactly the same method as it given in examples. So if some one can guide me
Thanks

I just found that there is a bug with Sun One Studio 5. It creates faulty JSP file to test the client for the web services. With above problem I tested my web services using different developing environment such as Jdeveloper 10g. I created client stub using wsdl file generated by sun one studio. And made call to my web service and all the parameter reached perfectly at service end point. And then I used stub class created by sun one studio for the client and made the same call. And it also went well. So the problem is with the test application (JSP File) sun one creates for my web service.
This is the majore problem i faced during the development. But still there is many problem along with this which is not seriouse enough but requires attension. I would like sun developers to make sun one studio IDE simpler and handy .
