ALV layout check

Former Member — Tue, 02 Aug 2016 20:20:59 GMT

Hello experts,

I have a program which shows an ALV using FM REUSE_ALV_GRID_DISPLAY. It has a button to save layouts and it works fine. However, I would like to check the layout name just before saving definetely. I mean, pushing save layout and once I write its name and accept, I want to check the layout with my own code. Is this possible? Is there any user exit available in this process or should I implement my code for the whole layout process?

Thanks in advance.

PD: I did research of this issue in SCN.

Any idea? I want to check the ALV layout just after saving it.

Probably not, but not sure. Can't you just find a place where to implement an implicit enhancement option? (enhancement framework)

Thanks for your answer,

I did not find anything in the function responsible for saving the layout. I believe that it is not possible.

Regards.

Add a breakpoint at function module LVC_VARIANT_SAVE_LOAD, execute, and debug "backward" (manually), you'll probably find easily a place to add your code.

I have not found a place for my code so far following your advice. Anyway, I keep trying. I will let you know in case I find something.

Hello Kishore,

Thank you for your answer. LT_DBDATA_WRITE_TO_LTDX and LT_DB_UPDATE_LTDXD are the functions which I need. Just after saving my layout, these functions are executed. Unfortunately I did not find any enhancement spot.

Regards.

Why do you say LVC_VARIANT_SAVE_LOAD has no spot to place a control?

i see a wonderful


form f25_initialization

where to place your checks within an implicit enhancement.

It also provides a flag to stop the execution of the FM!
