Related links are defined as "Links that access information which is topically related to the content currently displayed in the portal content area." they Helps users to quickly find information relevant to the context in which they are working.Automatically appears when the portal object they are linked to is part of a portal page.
Working in the Related Links Editor of the Portal Content Studio, the content manager can assign iViews and pages as related links to other iViews or portal pages. At runtime, the related links of all the visible iViews and pages in the content area, are accumulated and inserted into the Related Links iView of the navigation panel. The end user can click these links to pursue a specific topic
Whereas in case of Drag & Relate , relationships between iViews is based on Business objects.
Using Drag&Relate, iViews can be started from other iViews. The iViews are related to another with Business Objects. In a Drag&Relate operation, a Business Object is transferred from one iView (Drag&Relate Source) to another iView (Drag&Relate Target) as a parameter. Transfer and starting of the iView is done using by dragging the specified DRAG symbol with the mouse.
A Drag&Relate Source is an iView that contains Business Objects. Drag&Relate compatible Business Objects are designated with the symbol . In SAP BW, Business Objects correspond to InfoObjects of type Characteristic. With a Drag&Relate operation, the characteristic, a characteristic value and the logical system are transferred. When you only click on the DRAG symbol in a BEx Web Application without dragging it to another iView, the master data with attributes from the InfoObject Characteristic are displayed.

Portal Runtime error during 1, 2, 3 Drag & Relate?

Hi,
I have successfully install SR1 version of the EP6. I am attempting to complete the "1, 2, 3 Drag&Relate" weblog. During one of the steps you have to go to User Administration > User Mapping to set the Everyone group user mapping.
I am using sa id and the password I set during my SQL installation.
As I click save button after entering the input I get this error:
Portal Runtime Error
An exception occurred while processing a request for:
iView:
pcd:portal_content/administratrator/super_admin/super_admin_role/com.sap.portal.user_administration/com.sap.portal.user_mapping/com.sap.portal.userMappingAdmin/com.sap.portal.userMappingAdmin
Component Name: com.sap.portal.usermanagement.admin.UserMappingAdmin
User Mapping not fully available..
Exception id: 2:07_11/01/2005_0001_4582650
See the details for the exception ID in the log file.
Any ideas why this error is occuring?
Thanks,
Jin Bae

Hi Jin,
I think SAP note number 796540 will be helpfull to you.
It was known User Management issue which is not connected to any Unification feature.
Personal advice: try to restart Portal server.

Drag&Relate in SAP Portal 7.0

Hello experts,
I have a problem in SAP EP 7.0. I need to use Drag&Relate technology but in this version is not possible because this functionality is discontinued. The reason is that there is a technical reengineering of the Distributed Query Engine (DQE) technology.
But, what can I do? Is there any way to reproduce similar functionality?
Thanks in advance,
Belen

Hi there Belen,
I have the same problem, only that I am using EP 6.0 SP16. The DQE doesnt start because of the "Technical reengineering" and there are a number of related functions that are not available in the portal..
For example, I am not able to add Drag and Relate targets to iViews, there is no option for adding it in the detailed Navigation. There is also no Unification section in System Administration. I am really frustrated about it..
Have you found out anything regarding Drag and Relate technology and if it will be continued again in the future? Do let me know if you have found anything regarding it.
Thanks,
Sameer

Define main objects for Drag & Relate between BW 3.1 and EP6

hi all.
We are trying to implement Drag & Relate between BW 3.1 and EP6.
We have 2 different BW reports based on the same object "0MATERIAL". One of them should be a source and the other is the target. When creating the iViews for these reports the "main object" property has no values, therefor we don't see any symbol near the object we want to drag. The import of the "0MATERIAL" object from BW to the portal was successful.
Is it related to customizing the BW system or the portal?
thanks,
Sagi

I solved the problem - I added the BW alias before the main object name in the main object property. For example "BW.0MATERIAL" when BW is the BW system alias and 0MATERIAL is the object name.

Drag & Relate Icon not displayed

Hi,
While I am doing drag and relate scenario, the Drag & Relate Icon displayed in the iView's Preview. But when i logged into my portal it is not displayed?
After assigning the Super admin role, then it is displayed.Please let me know whether the Super admin role is required or else any other role to be assigned instead of Super admin role??
Thanks in advance.
Regards,
Senthil Kumar S.

Hi Senthil,
The user viewing the iview should ve the permission "full control " and "end user" for the system and iview. I guess for the super admin, the permissions are given correctly. Thats why you are able to get the Icon displayed.
Instead of assinging permissions to the role, set permissions for users.

Saravanan.

Drag & Relate scenario

Hello,
I have setup R/3 in the portal for drag & relate, and i have a custom iView which I want to use with the R/3 for drag and relate. the iView is the drag & relate target, it needs to be able to (when we drop "something" on it) get the parameters from the the object using the drag & relate context (?) and use them for further processing - i.e use the params in a query , etc. I would like to know, how exactly do i do that? Is that done programatically, or rather from the portal? Do I need to change my iView in order to enable it for drag & relate, and to act as a target? If yes, should i also do that programatically, or by setting up the iView properties? Thank you very much in advance.
Regards,
Angel

Hi Angel,
regarding your questions:
(1) Is that done programatically, or rather from the portal?
A: This is done in the portal.
(2) Do I need to change my iView in order to enable it for drag & relate, and to act as a target?
A: Yes, Changing iView properties.
(3) Change iView properties according to the iView type you use. Take the Unification Cookbook from SDN as a practical help for that.
If you need further help, please post again or let me know.
Merci and Best Regards,
Andreas

Drag & Relate between two BW reports

Hello together,
I want to implement the Drag&Relate functionality between two BW Reports via EP 6.0. I have configured the connection between Portal and BW with the report RSPOR_SETUP. The SingleSignOn and the import of business object is working well. After that, I took 2 BW testreports which were prepared for D&R. When I now drag the customernumber of report1 to the target report2, I get the error message "No relation found between the source and target business objects". The business object in both reports is 0CUSTOMER, so what relations should be set?
Where is the mistake, could anybody help me?
Thanks and regards.
Gerd Nedderhoff

Hi Gerd,
You have to link the two iviews. First double click the first iview. Then right click the second iview and make it as the target iview. Then in the navigation panel you see the other iview in the Drag and relate section.

Arun

Drag & Relate Query iView Problem

Hi,
I just trying the weblog

So all the steps mentioned in that i have followed properly but in Content Admin --> unification under Business Objects i do get sales and stores and i define them according to weblog as source and destination but under edit mode Relation Type is Empty which i think should be manual or something and all the other things are same as shown is screen-shot of the weblog and also in the enduser screen i get message
Query execution failed. Exception message: Error trying to execute a query statement against MetaMatrix: Error trying to establish connection to the EIS : null
So i have no clue what could be possible problem
Kindly Help
Regards,
Ricky

Hi,
Drag&Relate and Related links iviews are 2 different types of iviews.
1) Drag&Relate iview is part of the unification capability of the portal which can be used to get meaningful data by creating relations between business objects. Check
http://help.sap.com/saphelp_nw04/helpdata/en/76/c6693e54d6d112e10000000a11405a/frameset.htm
2) Related links iviews are iviews which are added as links or refernce iviews to existing iviews or pages so that it is easier to find them while navigating in the portal.

Drag & Relate SAP txn to external java servlet

We have a java servlet external to SAP portal that we want to interface to a SAP document. Using drag and relate we want to pass SAP document type and number to the servlet URL. Can some one point me how make that happen in Portal us9ing drag & relate?

Hi Jens.
You can use HRNPService for creating HRNP links.
The javadocs for HRNP will be fully available from SP10, but I will provide a sample code for creating HRNP links:
import com.sap.portal.unification.hrnpnode.IHRNPNode;
import com.sap.portal.unification.hrnpnode.IHRNPNodeFactoryService;
private String getHRNPLink(String systemAlias, String businessObjectName, String attribute, String value){
          IHRNPNodeFactoryService hrnpFactoryService = (IHRNPNodeFactoryService)PortalRuntime.getRuntimeResources().getService(IHRNPNodeFactoryService.KEY);
          IHRNPNode hrnpNode = hrnpFactoryService.createHRNPSource(systemAlias, businessObjectName, attribute, value);
          String link = hrnpNode.getHRNPLink();
          return link;
systemAlias: alias of the backend system in system landscape ("pubs_alias")
businessObjectName: name of the business object ("dbo.authors")
attribute: in MSSQL Server it is the column name ("au_id")
value: value to be dragged ("50").
getHRNPLink() will return a string in the following format: "hrnp://0:0/pubs_alias/dbo.authors/au_id/50" which you can drop on any unification target.
Hope this helps you, and you can contact me with any additional questions regarding this topic.
Vadim.

Drag&Relate - BI 7.0

Hi experts,
I would like to use drag&relate functionality in SAP Netweaver Portal 7.0-BI 7.0 systems. I read in some FAQs, that is not possible, but the help.sap.com (http://help.sap.com/saphelp_nw04s/helpdata/en/9d/02b2b4de384af8ae759e55738296f7/frameset.htm) shows, that it is possible form sps12. Do you now where can I found the documentation? Did you use drag&relate in BI 7.0?
Thanks in advance!
Edited by: Endre Halmos on May 26, 2010 5:06 PM

1) How can I upload the Old Statistics data( before upgrading to 7.0) i.e Query run time details and into these Infocubes.
>>I believe you can't as both are using the different mode / tables. You may try mapping data and load from one cube to another one or making a Multiprovider.
2) I find the standard query 0TCT_MC02_Q0200 is generated from the multiprovider 0TCT_MC02. The multiprovider 0TCT_MC02 is the join of infocube 0TCT_C02 and 0TCT_VC02 which is a virtual cube which is exact replica of the 0TCT_C02.
The BI process chain uploads 0TCT_C02. How does the virtual infocube 0TCT_VC02 contribute to the report.
>>Virtual provider picks up the current data while normal cube has data which is loaded into statistics cube as per your load schedule. so multiprovider provides the current picture.
3) Again I find the Data Manager Statistics (Details) infocube i.e. 0TCT_C03 is uploaded with 0 records.
Not sure...you need to check.
Hope it helps

Drag&Relate Target

Hi All,
I am trying to follow the following steps in CE 7.1 EHP1:
http://help.sap.com/saphelp_nwce711/helpdata/en/49/330a10fd695aa8e10000000a42189d/content.htm
But when I open an iview to edit, I am not able to set the Drag&Relate Target property to true as I am not able to find it.
Can anyone help?
Regards,
Malita

Hi Malita,
Its there in iView Properties just below domain property.
FYI:
To assign Drag&Relate capability to an iView:
       1.      In the Portal Catalog, right-click the iView you want to convert to a Drag&Relate-enabled object, and choose Open ® Object.
       2.      In the Property Editor scroll through the iView properties until you find the Drag&RelateTarget property.
       3.      Change the value of the Drag&Relate Target property to 1 and click Save.
Regards,

Drag&Relate enabled iViews with PDK

Hello everyone,
I want to create a Drag&Relate-enabled iView with PDK on EP 6.0 SP6 but I did not find any guides about this topic. Does anybody know how to do this?
thanks in advance,
Jens Harzer

Hi,
the new, enhanced, pure Java, Drag&Relate is being released at part of PP SP7 (Stack 05), and now is available to use as part of the Portal Platform.
It is very easy to create content that enable Drag & Relate using the simple iView Wizard (both 'Query iView' and 'Application Integration iView') as well as the Role Uploader - they all create content that is 'unification enabled'.
of course, it is not that simple, and one needs to define the right systems, use the correct templates and so on, but, it is possible (as well as using the newly Context menu notion instead of Drag & Relate).
I encourage you all to consult the Portal Platform documentation to see how it's like, we are planning for more roll out activities soon.
Thanks
Ori

Unification: Availability of Drag & Relate in Netweaver 2004s

Hi,
I found a comment in the SAP Help on the availability of Drag & relate functionality in NW 2004s.
http://help.sap.com/saphelp_nw2004s/helpdata/en/9d/02b2b4de384af8ae759e55738296f7/frameset.htm
I understand, that drag & relate will not be supported in NW2004s.
Since we are currently investigating this feature to enhance our portal applications, it seems we are having a problem here when changing the release.
I would be glad to hear about any experience with NW 2004s and this drag and relate feature.
Is it really no longer working ?
Thanks for any sharing of information on this topic.
Marcus

Hi Marcus,
I was also experimenting with Drag and Relate and found that DQE was not supported anymore..
Have a look at the SAP note 913483. It doesnt help much but gives a little more information about it.
Bye!
