LSMW 2001 infotype delete Recording

Hi,

I want to write a LSMW for deleting all the record IT2001 for any Subtype entering begda and enda in the period.

For Eg: if i select subtype as 0300 in date 01-01-2001 to 01-01-2003 and 10 records are present, then it should delete all 10.

Kindly advice me that how should, I go abt the recording and what all i should default other than perner, subtype, begda, enda.
