There is a need that we are optimizing material types used currently. So we are reducing no of material types which means we have to delete material types ( already materials exist for that material type. system allows to deleted from spro ). Will there be any impact for already created materials with such material types or PO's please let me know.
Or is there any alternative apart from deleting material types - basic intension is to avoide usage of such unwanted material types. how to control this
