Lock Activity using ABAP

Hi everybody,

We are using a Web Dynpro user interface for users to work with wbs elements and activity elements. They can open dialogues to edit those elements. Currently, if they open those elements by using the Web Dynpro UI, those elements are not locked. So, if someone else opens those elements in SAP GUI, the elements get locked. But the changes, the first user made, get lost, because he can't save those elements anymore.

How can I lock wbs elements and activity elements by using ABAP Code/BAPIs?

Thanks in advance!

  • Hi Mathias,

    How is the call being made from your UI to WBS/NWA in SAP? Is it an RFC or a web service being called in the back-end to fetch the data and then user makes the changes?

    If it is one of the two, the system will automatically lock the SAP objects while a user is performing his changes..

    Can you please check with your technical team on the interface used and what code is written..
