Can't you post the exact error message along with the message number?
Can't you just go to SE37 and check whether your function module is there?
You posted "Is the transaction number which i have give 1 to 99" - this sounds very strange, did you try it for all number between 1 and 99 times or did you really enter "1 to 99" when the function module expects just a single number?
Can't you just copy and paste this small code snipped from LSMW or be more precisely and technical in the information, should really be possible for an ABAPer who post in the ABAP forum
