If you created an material by error and you want to delete that material from the data base you can do it in this simple 4 steps. The only condition is that this material has to have no material movement recorded.
These are the steps:1
1) Flag material for deletion. transaction MM06
2) Run report MMREO001 - Selection of materials flagged for deletion and select the material
3) Run report MMREO050 Archive Materials to archive the material (some customisig settings might be required)
4) Run report MMREO110 Deletion Program for Archiving Materials to delete the material from the database.
These reports are called by the SARA transaction too.
