Hi Sefan
Using Sales Orders as an example
1. Mobile device user switches to "edit mode" for specific data
2. After that a sapgui users switches to "edit mode" too
3. Mobile user saves first ->
3.1 Mobile user gets an error message saying "Sales Order locked by SAPGUI user"
"wouldnt there be a chance to somehow transfer the backend enqueue/dequeue status via Gateway as a response back to the device?"
This is where you would need to implement some business logic, you would want to avoid getting too chatty.
I am interested in hearing peoples ideas.
One thought I had would be in step 1 to call a Gateway function which triggers logic where the system initiates a time based reservation in the lock table on behalf of the mobile user, would be interested in hearing from a Basis person of how best to do this or alternatives.
Cheers
