I want to do mass update in material master -units of measure in additional data of material.
It is not only to change ,
it should possible to update (create, change or delete) additional data corresponding to the values in the excel file
client is preferring LSMW with Batch input method.
I think these fields are not in Tables,it's available in SMEINH structure...
how to acheive this?? how much time it will take???
