SE30, Performance, nested loop

Former Member — Wed, 12 Sep 2007 15:26:30 GMT

Hi,

I looked at SE30 and found something verny usefull for my actual report.

The nested reports and how to do it better.

In the Documentation is written:

[...]

The above parallel cursor algorithm assumes that ITAB2 contains only

entries also contained in ITAB1.

If this assumption does not hold, the parallel cursor algorithm

gets slightly more complicated, but its performance characteristics

remain the same.

I would like to know the more complicated way, because I compare two tables which contain different entries.

Would anybody be so nice and help me?
