Could you gus please guide me how to call another application in current application. and also i want to pass values from current application to calling application. its very urgent for me. explain me how to all application(webdynpro)

Answer 1

Hi Venkat,
   When you select a row in your table , the entire row will be accessable through the lead selection, which means that you will get all the attributes and values.
Now you are goin to call a different webdynpro application which shows the details of this specific row.For this i dont think you need to pass all the data to the next application , you need to pass only the key data.For example consider the below table.
Table  Students
Student_ID
Student_Name
Student_Maths_Marks
Student_English_Marks
In this table , the key field is the student ID , which means that , if you have the Student_id , you can get the details anywhere you want.
So in the same manner , when you are calling the second application .You need to pass the key values to the second application through URL.
Let us assume that , i have created the second application , and in the DEFAULT plug of window of the application i have specified one parameter,student_id.Which means that , we need to pass the Student_id when i call this application.
Let my Second application name be DTLS.
With the WD_UITILITIES class mentioned in my previous post, i will get the URL for the application and with that URL , i will append student_id as a parameter.
concatenate lv_url '?'  'STUDENT_ID=' stud_id into lv_url.
Now you can call that URL directly.
Thanks
