Get View name from Navigational Link ID

[Former Member]

Hi All!

In runtime I have the navigational link ID, and from this I want to get the target view name. Is it possible somehow?

Maybe to load the repository.xml, and read the target view from it. Are there any handle class with which the repository xml can be processed?

Thanks for your help.

Regards,

Attila

Hi Attila,

In the past I have written one report which can parse the runtime repository information of given UI component into ABAP internal table. Then you can extract anything you want from that internal table.

However, if you are working on cross component navigation you can not get the target view name directly from navigation link since this kind of navigation is done with help of navigation object. Please find source code of my report below. You can of course wrap it into your utility class.

Best regards,

Jerry

Hello Jerry!

Thank you very much. This was exactly what I was looking for.

Thanks Leon also for the answer. I just wanted to know the the target view name from the navigational links, to save it to my custom table for a special customer claim.
