Error handling

Hi friends,

I am doing MM01 upload using direct input program with LSMW.

I want to know, how to handle the errors? i mean when i am running the LSMW, if some error occurs after say 100 records, how to handle it.

after correcting the error do i need to delete the 100 records from flat file??

i am just using direct input program from LSMW. when i execute it shows a selection screen for input file, this i am manullay executing in background without creating the job from SM36. is this the way or is there any other way to run the batch job?

thanks a lot.
