I use the feature to add Additional Tab using custom component because I need drop down list, alv and input field some in my CI include some in a specific table.
Therefore, I created the class according to the documentation for the non CI fields and it's working fine. But as the thread mentioned at first, I got the same problem and can't figure out how to save automatically CI fields into database.
If the customer-defined data is stored as fields in the relevant CI structure of the object, the data is updated automatically. SAP recommends this procedure.
What I don't get is how this automatic update works for custom WDA component? How component fields are mapped to CI fields?
I didn't use the save_data_ext method, I just follow the badi help :-). I'm quite new to this module.
What's the logic flow ?
- getting object
- call get_data_ext
- fill the CI fields in the structure
- call set_data_ext
?
Do I need to add some code in the different method of my component controller (on_after_save, on_cleanup, etc.) ? or if I just use the set_data_ext every time my CHANGE event is fired it's enough ?
in method ON_REPORT_CHANGES I call the get_data_ext, get data from my node and then call set_data_ext. But I specify on each object to call change method is there a way to do that at the change of tab ?
It's not very dynamic though, because I add a case/when on the node_name because I manage DPO, CTO and ITO object.
Anyway, I'm good now to continue If you have a better way to do things let me know
