Web Application designer : computation on two tables ?

Question

Hello .
I have 2-4 queries in same web template.
Can i compute using between cells of two queries using some class.
I know of a class CL_RSR_WWW_MODIFY_TABLE using which
i can modify contents of same table for formatting needs.
Is there some way to compute between cells of two tables

HI Deepali,
This is not that easy. And you need to do a lot of coding, which is not supported by SAP. But i will describe it in upper level.
In the Table where you want to add foreign Data, create a modify Class. The modify has a method called init. redifine that method. This method has as importing paramter a reference to class called cl_rsr_www_page.
This Class contains all objects of page. This class has a method called GET_PAGE_OBJETCS. Here you can get a refrence to the other data_provider which is most of the time of type cl_rsr_www_view. The view class has public attribute n_r_request of type cl_rsr_request. this class has a attribute N_SX_OUTPUT which is a structure of type RRX1_SX_REQUEST_OUTPUT. Which contains the query result. Here you can get the value of the other cell which should be inserted.
Now redifine the methods of the write the value in a specific cell , eg. DATA_CELL.
i hope this helps.
best regards,
