Dynamic sort ascending / descending
I am trying to sort an internal table dynamically.
In this table I have a number of field to use for an ascending sort and other used to sort descending.
I have writen the code to create two fields (character field) in which I concatenate the sort field names.
The result is :
sort_field_up = ' field1 field2 field 3'
sort_field_dn = ' field4 field5 field 6'
and then i coded :
sort itab by (sort_field_up) ascending (sort_field_dn) descending.
But I get a dump ...
has anyone ever done this ?
