Mass change of material master
I have a query regarding mass change to be done in material master. I need to update one value in the Material group 4 field in sales org view 2 in MM02 transaction for nearly 300000 materials. One option i find is LSMW and the other i saw is transaction MM17. Please let me know how feasible is this MM17 transaction? Is it possible to upload all the 30000 materials through MM17 transaction in one go and update the field? Will there be any performance issue if MM17 transaction is used?
Please give your suggestion.
