Pass parameter to dynamically assign datasource?

Post Author: bradness
CA Forum: Data Connectivity and SQL
I've been struggling with this one... I have a current set of reports that run on a single set of SQL queries. The problem is that at the end of each period (lets just say a year) the tables and queries are archived and relabled with <tablenameyear>/<querynameyear>, so that each query will pull the appropriate year's data. Can I pass a parameter to my reports that will tell the report which set of queries to use as the datasource? And can this be passed onto each subreport within the Parent report?
Thanks in advance.

SUCCESS! Thank you kcheeb for your help!
I don't know why it required that I do it this way, but it works.My report and 4 subreports used a total of 7 different tables (which were already defined in SQL database)I had to create all 7 tables in VB as follows
conn_string.open()Dim SQL as string = "SELECT * FROM mytable"Dim cmd as new sqlCommand(SQL, conn_string)Dim dr as sqldatareaderdr = cmd.executereaderDim nTable as datatable = new dataTablenTable.Load(dr)conn_string.close()
Then using some logic to determine object was report or subreport, I had to set the datasource for each table that was original contained in the report. Using
crdocument.Database.Tables("tableName").SetDataSource(nTable) for main report tablescrdocument.OpenSubreport("subreportName").Database.Tables("tableName").SetDataSource(nTable) for subreport tables

Pass parameter from dynamic page to form

I have a report that uses a link to pass a parameter (projno) to a dynamic page. This dynamic page calls a procedure which, using the projno, pulls information from four tables. Depending on who the user is and what phase the project is in, each heading can be a link to a form so that the proper user can update the project. For instance, the projetc manager can update the progress table during phases 2-9. So I want the Progress Heading to be a link to a form so that the project manager can update the progress for a specific project number. I tried to put the link in the procedure like this:
if iPhase in (2,3,4,5,6,7,8,9) then
          htp.p('<TD><a           href="/pls/portal/PORTAL.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=6803259033&p_arg_names=projno&p_arg_values='||projno||'&p_arg_names=_projno_cond&p_arg_values=%3D&p_arg_names=_sessionid&p_arg_values=" target="_blank"><FONT FACE="VERDANA" SIZE="2">Progress</FONT></a></TD><TD width="10"></TD>');
     else
          htp.p('<TD><FONT FACE="VERDANA" SIZE="2">Progress</FONT></TD><TD width="10"></TD>');
     end if;
But it brings up a blank form... no parameters are passed. Help!?

when I use :projno I get a "bad bind variable" error. But really, I don't think that's the problem. Using the code in my last message, I can mouseover the link and see the correct information:
http://spring.ous.edu:7778/pls/portal/PORTAL.wwa_app_module.link?p_arg_names=_moduleid&p_arg_values=6803259033&p_arg_names=projno&p_arg_values=14&p_arg_names=_projno_cond&p_arg_values=%3D&p_arg_names=_sessionid&p_arg_values=
When I actually click on the link however, this is the URL now displayed in the address field:
http://spring.ous.edu:7778/pls/portal/PORTAL.wwa_app_module.show?p_sessionid=2592
It strips the url of the projno information.

Pass parameter from dynamic navigation iView to WebDynpro iView

Hi All,
I know there are a lot of threads dealing with passing paramters from EP to WebDynpro using EPCM but actually I didn´t find a solution for my problem.
I have in the dynamic navigation area of the SAP Portal an iView based on a JSP dynpage. In the corresponding JSP I fire an EPCM-event:
EPCM.raiseEvent("urn:test.de:wochenb" , "passDataToWebDynpro" , evtData);
In the content area there is a WebDynpro iView. In this WebDynpro-application I subscribe to the event in the wdDoInit-method of a view:
WDPortalEventing.subscribe("urn:test.de:wochenb" , "passDataToWebDynpro" ,wdThis.wdGetDataFromJSPDynpageAction());
and I have an event-handler:
public void onActionDataFromJSPDynpage(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, java.lang.String dataObject )
    //@@begin onActionDataFromJSPDynpage(ServerEvent)
     IWDMessageManager manager = wdComponentAPI.getMessageManager();
     manager.reportSuccess("EPCM event testing " + dataObject);
//@@end
My problem is now that the event is fired correctly by the JSP Dynpage but the event-handler of the WebDynpro is never executed.
As info: the domain of the J2EE-Server the webdynpro-application is deployed to is identical to the J2EE-Server the portal runs on.
Can anybody help ?
Thanks !
Bernd

Hi All,
I found the solution by myself.
For information: Click in the dynamic navigation fires the event und forces the content afterwards to refresh. During the refresh the WebDynpro subscribes to the event in the wdDoInit-Method. This is to late because the event is fired before the refresh.
My solution is to use a setTimeout before the event-triggering in the dynamic navigation iView.

Bernd

How to Pass parameter to Custom Scheduler dynamically

hi ,
I am new to OIM.
Need your help in passing parameters dynamically to Custom Scheduler.
I have created Custom Scheduler by extending Task Support.
I have registered the plugin through API , using PlatformService.registerPlugin() method.
As I need to send the parameter(s) to this CustomScheduler, I have defined them in Metadata (CustomScheduleTask.xml) file as below and got it imported into DB
through weblogicImportMetadata.sh script by providing the path of the file.
<scheduledTasks xmlns="http://xmlns.oracle.com/oim/scheduler">
<task>
<name>CustomScheduleTask</name>
<class>org.schedule.custom.task.CustomScheduleTask</class>
<description>Fetch details of the given user_id</description>
<retry>5</retry>
<parameters>
<string-param required="true" helpText="Login Name">Login Name</string-param>
</parameters>
</task>
</scheduledTasks>
Iam able to import this plugin as well as register the plugin successfully. Now I have defined a job to which this Custom SchedulerTask is mapped.
Now in order to run this job(schedule task) I need to provide Login name( or id) which needs to be send as a parameter for the scheduler to get executed.
But while defining the job with this Schedule Task on OIM console, I was not able to define or pass parameter to this job. hence parameter is null in
CustomSchedule 's execute method .
Kindly help me how to pass parameter dynamically while running the scheduler from OIM console so that the execute method would be able to receive it.
Thank you in Advance.
Regards,
Kumar

Hi,
When you have created the schedule job for your custom schedule task, you should see your Login Name textfield in the schedule task. If not, then there verify your schedule task xml.
In your schedule class code, add:
public void execute(HashMap arg0) {
          final String METHOD_NAME = "execute :: ";
          logger.debug(CLASS_NAME + METHOD_NAME + "Entering Method - execute");
          try {
               String LoginName = arg0.get("Login Name");

Pass parameter to page fragment in dynamic region

Hello.
I am using Jdeveloper 11.1.1.3.
Can anyone explain to me how to pass parameter to page fragment in dynamic region?
My situation is:
I have only 1 page: index.jspx.
This page include 2 elements:
1. <af:tree>
<af:tree id="t1" var="node" rowSelection="single"
value="#{bindings.FpsrVO1.treeModel}" rendered="true" expandAllEnabled="true"
contentDelivery="lazy" initiallyExpanded="false"
contextMenuSelect="false" fetchSize="-1">
<f:facet name="nodeStamp">
<af:commandLink id="cl1" rendered="true"
actionListener="#{backingBeanScope.RegionDynamicBean.treeClick}">
<af:outputFormatted id="outForm" value="#{node.Name}" rendered="true"/>
<f:attribute name="menuId" value="#{node.Code}"/>
</af:commandLink>
</f:facet>
</af:tree>2. <af:region> :
<af:region value="#{bindings.dynamicRegion1.regionModel}"
id="r1"/>Region could be changed to 3 bounded taskFows wich have only one page fragment.
Can anyone explain to me how i can send <f:attribute name="menuId" value="#{node.Code}"/> from tree element to page fragment which will be rendered on screen?

You can pass a map to the dynamic region which would take the task flow parameters as key-value pairs.
<taskFlow id="dynamicRegion1"
taskFlowId="${backingBeanScope.TestPageBean.dynamicTaskFlowId}"
activation="deferred"
xmlns="http://xmlns.oracle.com/adf/controller/binding"
parametersMap="#{backingBeanScope.TestPageBean.parameters}"/>
When reloading the taskflow, ensure that the necessary parameters are loaded into the taskflow.
Check this example exactly based on your use-case:

In human task, dynamically assign group doesn't work

Oracle SOA 11.1.1.4
My bpel process invokes a human task.
On the human task Assignment tab, I assigned 3 users (by name), 1 group (by expression).
The group is configured in LDAP
When I tested the bpel process, I entered the group and other data required.
From the worklist app, I see the task listed. It is assigned to the 3 users, but not the dynamically passed-in group.
From the Audit trail, I saw all data I entered (include the group). Everything seems correct, but I still can’t make the dynamically-pass-group work.
If I assign the group by name in human task, it works fine.
The problem is: dynamically assign group doesn't work.
Please kindly advice.

Yes, it is possible assign a group as participant of some human task, passing the group name as parameter.
I have tested just now.
It works pretty well in SOA 11.1.1.4 (BPEL or BPM).
Make sure add a data parameter in your human task definition and pass a valid group name to it.
At the Assignment tab, in the participants' list, add a group, data type by expression, and set the value to the right xpath expression to the corresponding parameter.
For example: /task:task/task:payload/task:group
If it is not working look the SOA log files, probably you'll find some information about the error there. Maybe there is some problem with your jazn.com configuration.
You can also test if there is something wrong related to the group name, trying to transfer some task to the same group by the worklist.

Passing data to dynamic selection screen

Hi Guys ,
I need to pass some field values captured in my report to transaction FBL5N . The problem is that one of the fields which i need to input the value in FBL5N is a dynamic selection in FBL5N and is not in the standard selection screen . How do I pass the value to this field .
Any sort of help would be great .
thanks

If a parameter ID is assigned to the field with dynamic selection in FBL5N, you can pass the value by means of SET PARAMETER ID statement.

Import statement: pass parameter or variable in import statement ??

Hi All..
Is there a way to pass parameter or a variable to a url in the import statement..
I'll be using a url in the import statement, the url will be having a dynamic .rtf file...something like
<?import:http://#server#:#port#/xmlpserver/<mySubTemplate>.rtf?>
where <mySubTemplate> is dynamic..
I've been searching this thread for a while now and ended up close...
Import sub template dynamically
Thanks in Advance..

Have you tried replacing the mySubtemplate.rtf part with a variable, or replace the entire URL using a variable? Try using the same construct from this example in the Report Designer's guide (page 7-14, 10.1.3.4).
In Microsoft Word's Format Picture dialog box select the Web tab. Enter the
following syntax in the Alternative text region to reference the image URL:
url:{IMAGE_LOCATION}
where IMAGE_LOCATION is an element from your XML file that holds the full
URL to the image.
You can also build a URL based on multiple elements at runtime. Just use the
concat function to build the URL string. For example:
url:{concat(SERVER,'/',IMAGE_DIR,'/',IMAGE_FILE)}
where SERVER, IMAGE_DIR, and IMAGE_FILE are element names from your XML
file that hold the values to construct the URL.
This method can also be used with the OA_MEDIA reference as follows:
url:{concat('${OA_MEDIA}','/',IMAGE_FILE)}

How to get month value from custom calendar without passing parameter from SSRS in MDX query

Could you please throw some light to achieve below requirement?
I need to filter the data between two periods dynamically . The date calendar here works differently(ex:-Date 26-Aug-2014 will fall in period 7 which is last date and 27-Aug-2014 will fall in period 8 and it is first date of period 8),so I cannot go
with system date period/Month. Date Hierarchy is like YEAR,QUARTER,PERIOD ,WEEK and DAY.
I cannot use SSRS for passing parameter. Requirement is to extract last 2 period of data dynamically in Power Pivot with MDX.
Thanks Chandan

Hi Chandan,
You might try something like this
Tail(null:
Extract(
StrToMember("[FYDay].[DATE].&[ + cStr(Format(Now(),"yyyy-MM-ddT00:00:00")) + "]")
*[FYDay].[DateHierarchy].[Day]
,[FYDay].[DateHierarchy]).parent.parent
,2)
What it is doing is multiplying Day by the current date, which returns a set of one date with cardinality of (Date,Day). The Extract is pulling out just the datehierarchy Day. the the Tail() is getting it and the previous day.
Hope that helps,
Richard

Error while passing parameter in Oracle Jdeveloper

Hi All,
I was passed Crystal report viewer object From Servlet it is Running fine but one problem in that while passing parameter from that page to data base it is not supporting (The ok Button on page).
can any one tell me how to find Action Button (.Jsp page)
Because i am using .jsp page That was made in CR4E
in that i found only jsp code I have not get how to work Action of that button
Also another problem while making Viewer.jsp pge ..rpt-Crystal reports--->>Create Viewer Jsp->>Insert CrysatlReport viewer API code------->>>1.Connectparameterinthat report 2.connect the crystalreportPageViewer while makin this page i was running on Apache tomcat Server it is not displaying Anything only Displaying Blank Browser
Can Any one help me...
Sincerly
Amol

For your first question can you please be a little more clear as to what you are referring to? I am not familiar with an action button for the parameter pages.... what I can tell you is that we don't have any jsp code for the viewer controls, all of that is generated dynamically at runtime. We do have a viewer SDK that you can use to set properties on the viewer; information about this can be found in the [Developer Library|https://boc.sdn.sap.com/developer/library] in the Viewer SDK documentation book.
For your second question, I assume you are referring to generating a viewer page from a report in Crystal Reports for Eclipse. You will need to uncomment the viewer code (for some reason when the page is generated, the viewer code has block comments surrounding it). You will probably want to make sure the parameter code is uncommented as well.
In addition to this, there is a helper file called JRCHelperSample.java that contains all of the helper methods for the automatically generated viewer page. This can be modified in whatever way you wish to suit your needs.

How to pass parameter from 1 stored procedure to another stored procedure inside crystal report

Hi
I have several stored procedure in my Crystal Report. I am wondering if it is possible for me to pass a parameter to one of the stored procedure and to use the result of that stored procedure E.g. CustomerCode. To another 2 stored procedure to generate the report dynamically?
I have 3 stored procedure
The 1st one is used to gather information and process the calculation
another 2 stored procedure is used for generate the graph and both of them required to take 2 parameters. The 1st stored procedure will require 1 parameter (E.G. Reference Code) and will return a set of information including the data that could be use on the other 2 stored procedures.
After I added these 2 stored procedure, it requires me to pass 3 parameters to the report. I would like to know if I could only pass the Reference Code for stored procedure 1 and use it to retrieve the information for the other 2 parameter?
Thanks in advance
Chi

Hi Chi
To pass parameter from 1 stored procedure to another stored procedure, you will have to create sub report. In your case you will have to create 2 sub reports for 2nd and 3rd stored procedure and link those sub reports with the main report using Reference Code field in order to pass the values.
After creating the report when you will refresh the report, it will ask 4 parameters, one parameter for main report, one for the first subreport and two for second subreport to fetch the data correctly.

How to pass parameter when create view link

Hi,
I used R12 to implement OAF. I create a VO with paramenter such as SELECT item_code,parent_item_code,month_budget_id
FROM cux_ce_month_budget_lines_t
where month_budget_id=:1
But when I create VL for this VO. It seems the parameter :1 can not be passed.
Could some one to help lookinto this?
Best Regards,
Eileen

You donot need to pass parameter while creating the View Link. Once the view link is created then you assign the bind parameter to the master VO and execute the View link. The Child VO would automatically be executed.

Where a.DeptNo= b.DeptNo &WhereClauseIt's hard to guess, from an example like this with so many errors, exactly what you're trying to do.
Please post a description of the problem, including CREATE TABLE and INSERT statments for any tables you need (unless you can state the problem using commonly available tables, such as those in the data dictionary or the scott schema), a few values of a parameter (or examples of different user names, if USER acts like a parameter) and the results you want from the same data for each value.
For example
"In addition to the scott.dept table, I have a table called my_dept: CREATE TABLE my_dept ...
which has this data: INSERT INTO my_dept ...
I need a script such that, when user scott runs it, the results are ...
but when any other user runs it, the results are ..
As you can see, the difference is ..."
Table names must be explicitly given when a SQL statement is compiled. That's why I usggested a preliminary query; so by the time you compiled the main query, the table name would be known and could be passed in a substitution variable.
If you really want to do it in one query, you can do a UNION of two queries, one of which returns nothing because of the parameter. It's not very efficient.
