LSMW - Direct Imput

Hi Experts,

I hv couple of doubts in LSMW, they r,

1- In What situations I have to select the Direct Input method? Is it like that, for all Master data(MATMAS, CREMAS, DEBMAS), <u><b>always</b></u> I must go with Direct Input?

2- Can I create a Material in Material Master with Batch Input Recording method?

ThanQ.
