Two functionalities on the click of SAVE Button in the Planning Layout

Dear all,

Please share your experience with me if you have had a similar requirement.

I have a Save button and a calculate button on a planning layout.Now the requirement is to include the functionality of the calculate Button in the SAVE button.

I have come accross a How-to Guide which talks about including a Global planning sequence after clicking a SAVE Button and Before executing the layout.

But how do i implement the same for including the functionality of another button (calculate) instead of the global planning sequence.

Your suggestions will be of great help to me.

Thanks,

Ramya.
