BADI FTR_CUSTOMER_EXTENT Implementation for Facility creation - TM_61

Question

Hello Experts
I am trying to add new tab in the create facility transaction and I feel that the right BAID to do this is FTR_CUSTOMER_EXTENT. I am not able to update the new values in the screen to the database table. I check in the forum and there are many questions for the same but there is no clear answer for the same. Request your help in letting me know how this can be achieved.
I have also checked the same Function Group FTR_CUSTOM_BADI_SAMPLE but still I am not clear as to how I can achieve this.
Thanks in advance

Hello Claudia,
I finally solved the problem, and I hope my solution may suite your problem.
The bigger problem I had was pass the data from the screen to the BADI itself, so I created a function group following the FTR_CUSTOM_BADI_SAMPLE in which I developed the objects.
Those are the steps I followed:
I enhanced the structure VTBFHA with the custom field I needed;
I created an implementation for the FTR_CUSTOMER_EXTENT
in EVT_APPLICATION_START method I called a function module (copied from the FTR_CUSTOM_BADI_SAMPLE_START) in which I started the subscreen I draw in new tab. (Please note that by doing this I now have the interface if_open_trtm_customer_data always at hand). Follow the instruction of the sample code or the http://scn.sap.com/thread/1534252 thread)
in the PBO of the subscreen I retrivied the custom data via GET_CUST_DATA of the IF_OPEN_TRTM_CUSTOMER_DATA interface and pass the data in my screen fields. In order to do that I called a function module developed in the same function group, so that the interface is ready to be used.
in the PAI of the subcreen, once the data is entered I pass the new data via  SET_CUST_DATA of the IF_OPEN_TRTM_CUSTOMER_DATA interface, again developing a FM within the function group of the EVT_APPLICATION_START custom function module I used.
I am sure there must be a better solution, but it owrked pretty fine for me, so I hope this my help you as well.
