- Why I've created FALV although SALV classes are provided by SAP?
I know SALV classes although I haven't used them often. The main reason was that they don't provide edit mode. So at the end I've always worked with cl_gui_alv_grid class so then whenever users decided that they need one of the field to be editable then I can do it in few seconds/minutes.
- But there is a way to make SALV editable!
Yes, I know the solutions of Naimesh Patel (found here) and Paul Hardy (in his ABAP to the Future book) and some other folks to make SALV editable. But In my own opinion, especially when you're at least on 7.40 with SP5 making SALV editable is not needed as you can fast create ALV Grid which does everything you want. To be clear the big advantage of SALV, to call grid output of table in two, three lines when you goes to the code you'll see it's nothing more than call of REUSE_ALV_GRID_DISPLAY... really old FM, which at the end use CL_GUI_ALV_GRID.
- Direct reasons
As I used CL_GUI_ALV_GRID so often then I came up with an idea to do some class which will make the creation faster, but I never had time to do it at work. You may know it, because of the time pressure you choose to create report/program/solution in the way you're doing from years ... and then comes another task....and another....
So I've decided to do it at home.... yeah I'm crazy. But at least some of you can also use it.
I've worked on this on 7.40 SP8 but this should work also on SP5 as well. Sorry for the users bellow that versions but I'm so used to use new syntax that I couldn't force myself to use old way of coding.

- Faster setting of layout and field catalog attributes
- Easy switch and copy between popup, full screen and container version
- Easy toolbar handling (in grid and in full screen/popup using Dynamic GUI STATUS & TITLE with ABAP code )
- One place to handle user commands of full screen/popup call -> event user_command
- At the beginning let's clear Function Group memory using FM 'CP_CC_S_REFRESH_DATA'. Just for the safety reasons :-)
- Then let's load BOM header data to FG memory. If you want to do mass transaction then you would probably want to fill selection table i_cpsc_bom_sel with more than one BOM number, it will be then faster than calling FM 'CP_CC_S_LOAD_COMPLEX_BY_BOM' separately many times.
- But header data is not enough, we should do same thing for BOM items using FM 'CP_CC_S_LOAD_COMPLEX_BY_ITM', as Items belongs to different work area in CEWB.
- Once we loaded data to memory we can start copying, firstly we need to call 'CP_CC_S_BOM_PROVIDE_BY_MBM' to get source header data and then use its export parameters in FM 'CS_CL_S_MAT_BOM_CREATE_BY_COPY', which is doing copy of a header data.
- Once it's done we have to get source items from memory using 'CS_CL_P_ITM_PROVIDE', and then use it for copying items to our target BOM in 'CS_CL_S_ITM_CREATE_BY_COPY'.
- At the end, when everything is fine, use FM 'CP_CC_S_SAVE' to save your changes and commit your work.
