Doubts in LSMW

HI,

Experts I have following doubts in LSMW.

1. Before uploading into the database, if at all we need to perform some convertion say UNITED STATES or U.S.A into US. Can this be done in LSMW.

2. After writing an LSMW for a transaction how would the user run this application, ie should he do all the 12 or 14 steps on the screen of LSMW.

3. Can LSMW be run on transactions where there are lot of popups and table controle applications.

Kindly help,

Thanks in advance,

Ram.
