can I use logical databases in a WebDynpro ABAP program?

I need to build a WDA screen that is similar to the SAPDBPNP selection screen (user can find the personnel number based on several criteria, such as last_name/first_name of the employee). So it seems that the existing logical databases have already many nice features already built (like the selection screens, the logic behind the screens etc). So I was wondering if/how I can use them in my WDA application.

Hello, Tiberiu.

You cannot use LDB directly within your WDA programa. BUT, you can fetch results from this LDB by using FM LDB_PROCESS. This function module can be called anytime from any kind of ABAP program. But you will still have to create the screen, as it only processes data, not screens.

I do not think that inclusion of a logical database's selection screen is supported. This is actually old technology, and I think SAP may be steering away from this.

That is a shame. The LDB created the selection screen for you and let you increase/decrease selection fields. Using that function instead of an LDB will be much work to implement in ABAP Web Dynpro.

I have the same issue. I want to build a Webdynpro ABAP ALV grid to access HR employees and their infotypes. On the R/3 side, the logical database provided the initial screen, the filtering of employees to process, and authorization checks.

So, are you saying I will have to build all this stuff myself in WebDynpro ABAP ???
