How to save the configuration?

Hi, we prepare to use SAP VC in company. I can input the configuration in CU50. I want to use the configuration which I input last time. I find that in CU50, Value Assignment--> Save temporarily--> Save as/Save . But this is not helpful. When I exit CU50(or VA01) and come again , the saved configuration are missing.

Could the configuration be saved forever?

Thanks
