Doubt regarding webdynpro cache

[Gauri]

Hi all,

We have one webdynpro for Java application which calls a BAPI in the back-end R/3.

Now we have done some validations suppose for customer number for checking if the number entered is existing in the back-end or not.

For the first time the user enters the wrong value and the BAPI gets triggered to check if the customer number is correct or incorrect but if again the user enters the same wrong value or any other incorrect value then will the BAPI get called again or there is any cache maintained at the browser level or at the server?

Thanks and Regards,

according to my understanding of your quastion is that you are cliking a button providin some data to the bapi, right, then every time the bapi is getting called, if you want to avoid this, you can get all the values in anode and you can do the validations in the webdynpro application in the front end also, that will increase the performance of your application, if the user entered value is correct then only you can excutres the bapi in the backend system.

Cheers,
