UWL object link missing parameters when jump to external page via portal

We configured SWFVISU in ECC to jump out to an external application via a portal page. Our resultant URL looks like this:
http://XYZ:50000/irj/servlet/prt/portal/prteventname/Navigate/prtroot/pcd!3aportal_content!2fevery_user!2fgeneral!2fdefaultDesktop!2fframeworkPages!2fcom.xyz.portal.frameworkpage!2fcom.sap.portal.innerpage!2fcom.sap.portal.contentarea?NavigationTarget=ROLES%3A%2F%2Fportal_content%2Fcom.xyz.pct.xyz%2Fcom.xyz.pct.rols.func_Sales_Representative1%2Fcom.xyz.pct.wrks.s.func_Sales%2Fcom.xyz.pct.pgs.func_Order_Accounts_OA&uname=USER.CORP_LDAP.mdeklerk&langu=EN
BUT the work item object link parameter i.e. Sales Order No. does not get passed/attached to the string. What are we missing?

It is passed as an implicit UWL parameter and will not be displayed in URL. You can read this parameter from webdynpro application.

Missing Parameters when JSP Forwarding

I am having difficulty with passing parameters when a forward occurs from
one JSP to a second JSP. When I try to get those parameters on the second
JSP I am getting nulls since it never actually receives them as parameters.
Here is what the code looks like ...
first JSP
======
<jsp:forward page="second.jsp" >
<jsp:param name="arg1" value="hi" />
<jsp:forward>
second JSP
========
String arg1 = request.getParameter( "arg1" )
This situation is occuring for me on iPlanet Web Server 4.1. (Fyi, when I
use the same JSPs on Tomcat through JBuilder, the parameter is passed to the
second JSP.) I am wondering if if I am missing something on how iPlanet
wants me to do pass arguments when forwarding or whether I just need to find
an alternative way to accomplish my goal. Thanks in advance.

In your second JSp try using.
String arg1 = (String) request.getAttribute('arg1");
I'm not sure if this is correct but from my understanding of Servlets you can not set a parameter programatically without overriding the ServletRequest. However, you can set an attribute. If this does not work then the following absolutely will:
JSP 1
<% request.setAttribute("args1","hi");
<jsp:forward page="second.jsp"/>
JSP 2
<% String param = (String) request.getAttribute("arg1"); %>
Hope this helps

"Add Link" missing from Calendar after publishing sharepoint page

The "Add Link" is missing from Calendar when I publish the page. While in the edit mode, I can see the "Add Link" option. I also made sure I have the right view mode set for the calendar. I am using SharePoint 2013.

Hi,
I assume you are adding calendar web part to a page.
Please click somewhere in the Calendar web part and check if Events/Calendar tab appears, and try to add new event. If you highlight one box in the calendar, could you see the +Add as below:

Exchange Converts embedded link to http when Sending to External Recipients

Hello:
We use a product called ProjectWise internally. One of the features is to embed the link to a ProjectWise document in the body of an e-mail and send it to other users. When ProjectWise embeds the link, it is in the format:
pw://path_to_file
Obviously, this is very similar to the http format. The pw:// link allows the file to be opened natively in the ProjectWise software.
Here's the issue:
When sending to other INTERNAL users, the link flows through correctly. However, when it is sent to an EXTERNAL user, the link is converted from pw:// to http:// and is useless.
We can even send the same email to both Internal and External users, the Internal users receive correctly, the External users receive the converted link.
I am thinking that Exchange is somehow modifying the link when sending to external, but I can't find anything on it.
Thanks,
Tim

Hi Tim,
Base on my knowledge, by default, exchange system does not modify the content of the email, except you create some transport rule.
Do external user use exchange ? or any other email system?
In addition, the format of "pw://" is only useful for internal, when you open the "pw://" link from internet, Browse may automatically converted the link to "http://".
Best regards,
Niko Cheng

Missing Parameters when using .PrintToPrinter or .ExportToDisk

I am creating a viewer that will set login information and allow the users to view, print or export reports. VB.NET 2010 WinForms Crystal Engine 13.0.9.1312. All reports are external designed by various programmers.
The preview mode of my viewer is now working quite well (with the help of Don and Ludek most recently). Anything I want to see on screen works great in the regular Crystal viewer.
The problem is when I want to export to pdf or print to a printer without viewing on screen in the regular Crystal viewer.
If there are no parameters in the reports, both exporting to pdf and printing to any printer selected works.
When there is one or more parameters, it crashes and points to the line
crReport.ExportToDisk(ExportFormatType.PortableDocFormat, strFile)
or
crReport.PrintToPrinter(1, True, 0, 0)
with the message Missing Parameter Values.
Through some searching (and yes I have checked on this site and Google for "Missing Parameter Values") I have found one big issue is that parameter values have to be set after the .ReportSource is set. So before I changed my code, I never saw the Crystal Parameter prompt screen. Now I see it but still get the crash (though once I have had it go to printer honouring the Parameter in a report, but I can't always reproduce it and never when sending to pdf).
The reports may be designed by end users who are using my program. I will not know what reports they are or if they have even put in parameters. I will not know if they are date, string, number, discrete, range, multiple, etc.

      crParamFieldDefs = crReport.DataDefinition.ParameterFields
      'loop through each parameter and assign it the current values
      For Each crParamFieldDef In crParamFieldDefs
         crParamValues = crParamFieldDef.CurrentValues

         Case Is = "PDF"
            crReport.ExportToDisk(ExportFormatType.PortableDocFormat, strFile) '--> Error Triggers Here
         Case Is = "xls"
            crReport.ExportToDisk(ExportFormatType.Excel, strFile)
         Case Is = "xlsx"
            crReport.ExportToDisk(ExportFormatType.ExcelWorkbook, strFile)
      End Select
End Sub
This code doesn't work on my system, but my logic is as follows (as flawed as it is). Look through the parameters, find the current values and then assign them to the parameters again just before export.
With the code above, I am getting the enter parameter values screen in the viewer. Therefore, my assumption is that the report now has a current value(s) for the parameter(s). The loop will not require the program to know how may parameters there are or what the values or value types are.
There are a couple of problems with this. When I step through it, there are no current values, because the prompt doesn't come up with stepping through the code with F8. Second problem is that it is finding the internal parameters used for subreport linking ({?PM-xxxxx}). Third problem is that a lot of code I have looked at does not appear like it is assigning the reportsource to a viewer at all just to export or print to printer. So is it necessary to do as I have done here?
I am sorry this is so long and I appreciate anyone who has stuck to it this long. I am at my wits end trying to figure out how to make this work. I think there is a timing issue here but do not know how to resolve it. I just want the report to trigger the prompts if there are parameters, then send the report screen, to pdf or to printer depending on the user's settings for the report (it may be any or all three options). If you need more info, let me know.
TIA, rasinc

Hi
I'd like to look at this from the "how parameters" work point of view. Then let's see if we can drill in on some of the details.
The parameter prompt screen is driven by the viewer. E,g.; the screen will only be spawned on invocation of the viewer. If the viewer is not invoked (e.g.; direct print / export) the parameter prompt screen will not be displayed. Now, in your second post you say:
With the code above, I am getting the enter parameter values screen in the viewer.
This does not sound correct based on the above. E.g.; if the correct parameters are passed to the engine, the viewer should never be popping up the parameter screen. So to me it looks like the code for the parameter is not actually working. It looks like it is as there is no error as such. But as you get prompted, the engine is essentially saying; "I don't understand those parameters so as smart as I am, I'll use the parameter prompt screen to get them from the user on a silver platter".
Ok. Now to some troubleshooting. I'd pick a report where I know the parameter type and acceptable values ahead of time. Don't use date or date / time params to start with as these have other complication. Use the parameter code to set the value(s) - preferably one value (I like to keep things simple). If the parameter is passed to the report engine correctly, there will not be a parameter prompt and the report will simply come up in the viewer. Once this works, add in a code for printing / exporting and comment out the viewer code. The report should print / export without any issues (no parameter prompt, no error). Repeat the above with a multi-parameter report.
Then it will come to those date and date/time parameters. NULL handling, etc., etc. E.g.; this will not be trivial. And you will somehow need to know the parameter type (string / int / date) before you try to pass it into the report. More help:

Flash Player 10.1 - Projector exits full screen when opening an external PDF via FSCommand

I am finding that when I am in Full Screen mode and launching a PDF via a FSCommand, the projector will exit full screen mode.
I remember this being an issue in Flash Player 9, but 10 resolved the issue. Recently, with 10.1, the issue has come back.
For the full screen, I am using the code below on the first frame.
fscommand("fullscreen", "true");
fscommand("allowscale", "True");
Thanks.

Hi gurus,
I've created object link LFA1 in DC10 (I also have EKPO and EBAN object links). But when creating a purchase order and linking a document to it, it doen't create the link, it has the EKPO link but never the LFA1 link. When linking it manually via trx. CV02N I do not know where I can see this link. it is not visible in ME23N and also not visible in trx. XD03.
Where can I see and set this link properly?
kind regards,

RE-FX Object link is not working

Hi Gurus
I have added the object VICNCN (Screen Number: 500) in DC10 for a document type. Now i can link Real Estate Contract with a DIR in Object Link tab. When i double click the Real Estate Contract number in Object Link tab then the system will open the transaction RECN. So i hope the DIR is attached to that number.
But when go to transaction RECN and select the menu Extras--> Document Management then the system prompts a message to create a New Record. Suppose if click "Yes" then it shows a error "Model Not Found". Actually the Real Contract Number has already been linked in Object Link Tab in CV01N. But it is not working properly.
Can anyone please help me to fix this issue.
Regards
Vasim Raja. R

HI Nayeem,
Please maintain Authorization group 1 in Maintain screen for Object Link :
Maintain 1 in Auth. field. Then go to RECN, Extras, Document Management there u will find Creation of document from RECN.

Additional sap objects links in dms

hi, all
i have an issue in dms.
1] the custemer needs dms link with routing
2] needs dms link with bom header and bom item
i think,
case 1. needs additional object setting, plz explain in details
case 2 .dms not allows to link bom header and bom item. give sugession
rds
ben

Hi Ben,
for object link settings please see the following WIKI page for all necessary customizing steps:
https://www.sdn.sap.com/irj/sdn/wiki?path=/display/plm/ca-dms-Object+link
Generally all standard object screens are included in function group CV130, which could be displayed in transaction SE80.
For BOM header the object is 'STKO_DOC' and for BOM item it is 'STPO_DOC'. The screen are the following:
STKO_DOC: 0258
STPO_DOC: 0257
Regarding the routing link I think document could only be used in routings but not linked. So the document have to be added directly in the routing itself. Maybe note 372499 could be useful for this issue.
Best regards,
Christoph
P.S.: Please reward points for useful information.

Create Travel Expense Report link missing in ESS

Hello Gurus,
I am unable to see the Create Travel Expense Report link in the ESS Travel & Management tab. I have modified SPRO and details are as below:
1) In SPRO, I have copied the standard Resource (EMPLOYEE_TRAVEL_EXPENSES_SRV05) and Service (EMPLOYEE_TRAVEL_EXPENSEREPORT05) as new Resource (Z_EMPLOYEE_TRAVEL_EXPENSES_SRV05) and Service (Z_EMPLOYEE_TRAVEL_EXPENSEREPORT05).
2) I have changed the URL Parameter in Z_EMPLOYEE_TRAVEL_EXPENSES_SRV05.
3) Later I have deleted the new "Z" Resource and Service that I have created in the SPRO, so that I wanted to default back to the standard.
After deleting the "Z" Resource and Service in SPRO, I am not able to see the "Create Travel Expense Report" link from the Travel and Expenses area page in portal. Though I was able to execute the iView directly from the Portal PCD.
Did any one got similar kind of problem ????
Could you please reply with your suggestion or advise how you have fixed this problem.
Thanks for any help.
Ram.

Hi Bharathwaj,
Thanks for your helpful answer.
I have checked the Area Page EMPLOYEE_TRAVEL_ERP2005, but I don't see any entry for services.
It has Area Link Text, Picture Resource, Area Link Type and Link Resource only....
Can you suggest if I have to see any other setting ??
Thanks for your help.

Attachment error: Object Link type   in UWL

Hi,
This is regarding the UWL - opening the attachment.
we have integrated the solution manger to the Enterprise portal where
the workflow tasks of the solution manager will be displayed in the UWL
of the Enterprise portal.
The workitems are displayed properly, but when we try to see the actual
work item attachment it is giving error as follows:
"Attachment error: Object Link type . See log file for details "
The detailed error we have taken from the UWL.log, which displays as
follows:
" Mon Mar 12 20:45:42 GMT+05:30
2007:com.sap.netweaver.bc.uwl.core.connect.webflow.util.ObjectLinkException: Mon Mar 12 20:45:42 GMT+05:30 2007 CRM Context service has not

The URL which goes like this:
http://ep6devn:50000/irj/servlet/prt/portal/prtroot/com.sap.netweaver.bc.uwl.ui.UWLInformation?key1=AttachmentError&key1_param1= Object Link type .
Similarly if we try to open the same attachment in solution manager by
logging at SAP-GUI frontend i.e. through Tcode:SBWP and selecting the
workitem, choosing the objects and attachments. it is displaying the
actual message.
Enterprise portal current status: EP 6.0 NW2004-SP16

Error message when searching for an object link within EasyDMS

Hello,
I have a problem with the easydms system. Everything works fine except searching in the object links. When I want to define an object link and I don't know the name of the object I try to find it with the help of the search function within easydms (within the object links).
But the search always delivers an error message:
"Missing authorization check to display master data"
Does anybody now what to do?
Thank you for your help.
Best regards,
Markus Sigl

Hi Markus,
When you try to do this the BAPI 'BAPI_HELPVALUES_GET' is used. There are some authorization checks that are being performed for the object. These authorizations are maintained in the table BAPIF4T.
For the above said test data, you are trying to get the help values for
the relevant field (e.g. EBELN: po_number).However,in table BAPIF4T the corresponding authorization for the data element ebeln is not maintained. And so you are getting this error.
So, when you maintain the below record in the table BAPIF4T,you will
have the corresponding authorization and you will not get the error
anymore.
sample entry:
Object type - ' '
Object type component - ' '
BAPIF4T-DTEL - 'EBELN'
BAPIF4T-FNAM - 'PLM_HELPVALUES_AUTHCHECK'
Best regards,
Christoph
