Program for Material Master

Dear All,

i have a requirement in which i need to develop a LSMW/BDC/BAPI for updating material master.

the user will upload an excel sheet with all the necessary fields in a specified format (if BDC is used).

i came across a t-code MMZ1 for creation of a material. the tcode is similar to MM01.

the difference i observed was that that in MM01 the views are of dynamic nature whereas in MMZ1 the views are of static nature.

i request all to further differentiate between MM01 and MMZ1 and also if i go for LSMW, which tcode will be more appropriate? MMZ1 or MM01 and why?

Thanks & Regards,
