List of Available Components for Component Usage

[amy_king]

I wonder if anyone knows whether there is SAP documentation anywhere (for any NetWeaver EhP level) that lists all the available components that may be used as component usages? For example,

• SALV_WD_TABLE for SAP List Viewer
• WDR_SELECT_OPTIONS for select-options
• ...

I've looked in both help.sap.com and scn.sap.com but I've been unable to find a single place that lists all the available components one might use as component usages. I suspect this must be documented somewhere but I've been unable to find it.

Cheers,

Amy

Hi Amy,

unfortunately, I am not aware of such a library either. It's probably the same as with function groups. Some are reusable, some are not. Web Dynpro as a technology is nowadays widely used in many SAP modules. So even for SAP it might be difficult to build such a reuse library - especially since true reuse might only be done at FPM level in future.

As it is the case with the function modules of some of the famous function groups: to know what is available and how it can be used would be consulting knowledge that is built over time by project experience.

Best regards,

Thomas

Hi,

I too didn't find any documentation but, You can check the table WDY_COMPO_USAGE . In this table, USED_COMPONENT field contains the component usage name.

You can write a small program to fetch data from the above table and sort and delete the adjacent duplicates of used_component field will returns you all the component usage names.

Hope this helps u.,

Kiran

Thanks Kiran. Table WDY_COMPO_USAGE did reveal some that I didn't know about, which is a good start.

Hi Amy,

    SWDP_REUSABLE_COMPONENTS-> Check this Package. It consists of all the to be used Components.

Regard's,

Thanks Shivesh,

This package does contain a few web dynpro components, but I notice that SALV_WD_TABLE, for example, belongs to package SALV_WD_UI, so SWDP_REUSABLE_COMPONENTS doesn't appear to be the complete set of all "component usage" components.

But thanks for the tip, this package does appear to be another piece of the puzzle.

Cheers,

Amy
