Guided Procudure - Webdynpro Application

Question

Hi All,
I have a Webdynpro application in Which Iam creating entries in a Custom Table. I have a view with all the input fields, when the user hits SAVE button after filling the input field Iam saving all those values in my Custom database table.
Now, the requirement is, before I save the values in table some one needs to approve it. Upon approval I have to save that.
Is it possible using Guided Procedures? I just started learning Guided Procedures.I could see that the Webdynpro application can be called from Guided procedure, but I would like to know how my scenario will be achieved.
For example, Do I have to use two different applications for that? and where to trigger the process. Can I trigger in my Webdynpro application?
Please give me the steps.
Thank You,
Suresh.

Hi,
yes it can be achieved using Guided Procedures.
Standard way is to create a Web Dynpro Callable object (please refer to:
https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/50d74ada-0c01-0010-07a8-8c118d408e59 ).
As far as I remember you need to implement some GP interfaces in Web Dynpro application, so that Web Dynpro application can be treated as callable object and
it can be included in the GP process. Thanks to these interfaces you also pass output data to other callable objects in the process step.
For example in your case, you could have a Web Dynpro callable object in which user fills data, and when he clicks the SAVE button then you will pass output parameters
to the next callable object (which in this case would be some approval callable object - please refer to the above mentioned document).
After approval you would call another callable object, which saves the data to the database.
Of course you can map context data between these process steps so you know which data to save.
After you create a process you can then create an iView which for example triggers this process.
I hope this info helped.
