Tree OOPS ALV - Need to display header & items of the sales order in oops
I need to display some of the header fields of the sales order & items in the oops alv, could you please let me know how to achieve this. I know FM - 'REUSE_ALV_HIERSEQ_LIST_DISPLAY' but how to achieve this through oops alv.
it is not possible with that function in OO .
you can try with class cl_salv_hierseq_table
Just check this Rich's article
if you don't want that then you may have to use ALV tree.
