How WebDynPro knows that user changed ONLY 3 fields data in interact. form

[former_member202077]

Hello,

Pls clarify me that,

I am developing a visitor info interactive form, the user opens the EXISTING visitor info FORM and changed some field value/data, say address fields in the form.

Then, How i (WebDynPro componenet) will know that the user has changed the Street, City, Telephone number etc address details? I knew that basically WD gets all the PDF form conetent via 'pdfSource' peoperty in binary format......but, how can i differentiate that among all the 100 fields, user has changed ONLY street, city and tele number? so that, i will update ONLY these 3 fields in SAP tables by using the associated BAPI

Thank you

Hi Srnivas,

In Java we have the method isChanged() in the different context nodes and attributes. Check if you have that method in ABAP too.

Thank you,

I checked METHODS tab of my_view (where i assigned interactive form UI), i did not found any such method! Then, how WD ABAP is handling it!
