A wiki for myself and everybody who is interested in developing ABAP using POWL(s).
Most of the content will answer questions on how to use POWL. So if you also have experience with POWL and know some cool features not listed here, please leave a link or just contact me via SCN or email.
POWL A very big resource of POWL with a lot of links included
HowTo Guide with an Powerpoint -- Official Site <-- This is really impressive. You won't need more information to develop and publish your first POWL
How to Use POWER Lists <–A cool guide to hand to the users which need to work with it
Helpful classes and interfaces:
IF_FIP_UI_POWL_CONSTANTS -->FIP POWL Feeder UI Constants
Put a color into a specific field:
Fieldcatalog - fill color and set the ref_field color (1 to 19 is allowed)
Put a button in each line
Put a button in specific line
additional to the doing above you just need to perform two more steps.
First is you have to define a field in your structure which is filled with active flag ( it is just a X, so you should use the boolean) The example here uses the highlighted field AUTH.
This field is now additional added as a referencefield to the field-catalog. (I didn't use a constant on that, because I believe if someone changes the fieldcat any time, it should catch the eye)
Now that we have a button we also need to define an action_id behind. That means, we need to define the button a little different.
The constant gc_action_release contains value RELBL which is also a column inside the structure (see above for more details).
Important sidenote is, that the displayed text is just a reference of this field! So as handled above the field text is useless in this context!
Through this you are now able to recieve the action_id ('RELBL') inside your method handle_action and react in a proper way
Now there is a small hint missing. What about the changed rows. If you want to have a message appering that data is unsaved as seen below
use these two parameters of method handle_action
e_result_lines_changed <-- set it to get the information.
After your implemented processing set the e_changes_processed to true, at that moment the popup will not appear anymore.
Navigate from your powl to a transaction
Include a progressbar in each line

Transaction POWL_EASY - A HowTo Guide and what the easy stands for.
Overview of POWL-Packages
I will add several sites and demos for the different possibilities over the next month. So stay tuned
Overview picture of necessary transactions (only customizing)
This is an overview of the "old" transactions which shows how these work together. Today you are also able to do all these steps via powl_cockpit, but for understanding purpose I like the single transactions more.
Here are all listed:
|Maintain POWL categories|
|Easy-POWL Feeder Builder|
|POWL_QUERY||Maintain POWL Query definition|
|POWL_QUERYR||Maintain POWL Query role assignment|
|POWL_QUERYU||Maintain POWL Query user assignment|
|POWL_TYPE||Maintain POWL Type definition|
|Maintain POWL Type role assignment|
|POWL_TYPEU||Maintain POWL Type user assignment|
POWL Reports <-- Good overview of the different Reports which help you to maintain your POWL-Load
POWL as Odata ← You can transform every powl you ever made - But it is just the Select-Criterias and the get_objects (No Actions are transformed)
