i delete all of the existing lists of material type in oms2, and i can't use the function of new item to creat new list. the error info is no existing lists of material type. in the sap help doc,it says that when creat new list ,it can use the function of copy.but now how can i do?i suggest if new item doesn't work,the last list should not been deleted.
If your system is setup in a way that you can compare customizing from your production system with the development system (and you have authority to do so) then you should be able to get it back from there. Go to OMS2, select from menu Utilities > Adjustment
alternative:
Your Basis admin can usually access client 000 which has the SAP provided customizing and should be able to transport it to your development system.
