How long did it take?
I just used COND_A last week and did not make any negative experience with run time.
I had an average of 13650 IDocs per hour
If I compare this with my customer load then it is extremely fast, here I had only about 1100 per hour
What exactly is slow?
the idoc posting (which has nothing to do with LSMW) , or the read process, the conversion step, the IDOC creation step in LSMW?
