Variable Exit - WEB Issue

Hallo everybody,

I am new here, just gaining the experience in BW- BPS area.

I am writing my thesis and a part of it is a small BPS rototype.

I have the following problem:

In web interface there are 3 Variables: Customer, Country and Project, all CHAR, drop-down. Aditionally, Customer and Country are attributes of Project.

Country is of Exit type. Function module read all countries for previously selected cutomer from the MD table of Project.

Then, Project is also of type Exit, and function module read all project for selected customer - country combination.

In does what it is supposed to do, but when I change the selection of e.g. customer, the selection list for country stays unchanged. The same is with project.


MD Table:

project customer country





Current selection is cust=1, country =1 and project=1. Now, I change the customer to 2, but the selection list for country is still 1 - and it is supposed to change to new country selection containing 2 as well. In this way I cannot change my selection to other projects. Buffering in off.

The other problem is, that when I select customer 3, which is not in MD table of Project (no Project for selected customer) but it is defined as variable value and in MD Table of customer, I get an internal error. Appropriate error message should appear (is in function code), but it is not.

I hope you have some how to overcome these problems.

Thank you in advance

    Hello Marcin,

    welcome to the group and good luck with your thesis!

    You have to set the property "Update upon Change of" of the depending variables accordingly.

      Hi Marc...can we create a variable on WAD? When we create a variable on query or function, these variable appears as pop up when we execute the WAD. On WAD we have the drop down option (which can be mapped to a characteristic). The values of the drop down is populated form the query. Can we have a variable which is similiar to a dropdown but we can play around with variable types like exits/authorizations.
