Reg:Folder Source in Admin

Question

Hi
I have a question, In a Business Area i want create two folders F1 and F2.
For F1 the source will be a database table on which i have logged on now.
My question is "Can i specify/select a table as source for folder F2 which is coming from different Database with some DB link in Discoverer ?" I am using 10.2.X.X version.
Any advice would be of great help.
Thanks in Advance.

Hi
There is a gotcha with this in that if there is a schema in the local database by the same name as the schema in the remote database you will not be able to import the definition for any of the remote objects. This is a known bug.
The workaround is as follows:
1. Create a dummy folder in your business area that points to a known object in the local database. Make sure also that you have only one item in the folder.
2. Determine the database link.
3. Determine the owner of the data.
4. If the owner’s schema does not exist in the local database, use Discoverer’s normal Import folder from database procedure.
5. If the owner’s schema does exist in the local database, continue from here.
6. Locate and click on the Dummy Folder heading.
7. Press CTRL-C.
8. Click on the business area heading.
9. Press CTRL-V to paste a new copy of the template.
10. Right-click on the copy; and from the pop-up list select Properties.
11. Rename the folder and give it a new identifier.
12. Click on <Default Database>.
13. The Choose Database and User dialog box will open.
14. Click anywhere in <Default Database> and from the drop-down list select the actual database that you want to use. The system will display a list of all users in the new database.
15. From the list of users, select the owner that you want to work with, and then click OK.
16. Discoverer will tell you the folder is invalid. When it displays the warning, click OK.
17. The Folder Properties dialog box will now have the Database and Owner properties populated.
18. Click in Object. Discoverer will display the Choose Table or View dialog box, with the Owner selected in step 15 highlighted.
19. Click the + key alongside the Owner. Discoverer will now display a list of all database tables and views owned by the user you selected.
20. From the list of objects, select the object you want to import, and then click OK.
21. The final settings on the Folder Properties dialog box should now have the correct settings.
22. Click OK.
23. Right-click on the new folder; and from the pop-up list select Refresh.
24. As you only have one option, click Finish.
25. Discoverer will now import the new data definitions and present you with a Refresh screen.
26. The origina named item in your folder may or may not be available. If it exists in the new table you are fine. If it does not exist you will see it flagged as being unavailable. If Discoverer does flag it as being unavailable you need to check the box alongside.
27. To complete the refresh, click OK. Discoverer will refresh the folder and it will now be available for use within your business area.
I hope this helps
Best wishes
