Im modifying an standard program (RLINV020) to add fields to alv result, but I see that there's a property in REUSE_ALV_LIST_DISPLAY (I_BUFFER_ACTIVE) wich I don't know how it's works and what is the difference between activate and desactivate it.
If i_buffer_active = 'X' then the fieldcatalog and other information will be retrieved from the buffer instead of what you pass to the function module.
If i_buffer_active = 'X' then the fieldcatalog and other information will be retrieved from the buffer instead of what you pass to the function module.
If i_buffer_active = 'X' then the fieldcatalog and other information will be retrieved from the buffer instead of what you pass to the function module.
Whatever is being displayed currently(Before you make that i_buffer_active as space) is the content of the buffer.
It is like this.
for the first time, whatever is the fieldcatalog you pass, will be considered.
Every time from then, the same that which has beed displayed wiill be in the buffer.
If you don't want to change the code , but to clear the buffer, you have to run the program: BCALV_BUFFER_DELETE once.
then whatever changes you did will be affected in the output. From this point onwards, your field catalog will be stored in the buffer(Until you run the BCALV_BUFFER_DELETE program again).
