ALV Sort functionality

[Former Member]

Hi

I have a internal table with one column index where some index are stored for some processing. This internal table is used for ALV display. Now suppose I sort the on the basis of one column. Now the ALV displayed is in sorted form. But is the internal table order changes?? How to keep track of the which record is placed were in internal table??

IN MATNR.

the internal table is sorted also, not only the display

if you are using reuse ALV function modules, you can get contents of your table by calling FM REUSE_ALV_TABLES_GET
