Hi Isha,
You can achieve your requirement by using either TABLE ui element or ALV in web dynpro.
Please follow the below steps: ( By using Table ui element )
- Create a custom table for storing data ZTR_DATA
- Create a context node MY_DATA by using ddic structure ZTR_DATA with cardinality 0....n
- Create an ui element TABLE on layout of your view and bind it to the context node MY_DATA
- Go to method WDDOINIT( ) of your view, write the logic to get the data from ZTR_DATA and bind it to the context node MY_DATA by using method LO_NODE->BIND_TABLE( new_items = lt_data )
- On action of SAVE button, you can read the data of context node ( table data ) by using method lo_node->get_static_attributes_table( ) and save lt_data to ZTR_DATA
Hope this helps you.
Regards,
Rama
