What are the ways we can block source list ?
You want to block source list or a source(vendor)??
In case if you want to block the source list then dont create a source list by checking the tick mark for source list in material master.
In case if you want to block a source then you have two ways, block the vendor completely means thsi vendor is not used for procurement of any materials at all. in case if you set block of source in the source list, means this vendor is blocked only for this material in the source list. other materials he can procure.
Thanks & Regards,
