Suse repository add/remove

In case that I add SUSE product from SUSE subscriptions and that then create products and under products create let say 5 repository and I don’t need all repository and I remove 4 repository and after some time I would like to have all 5 repository how then I get them back?

example:
under SUSE Customer Center I choose:
SUSE Linux Enterprise High Performance Computing 12 SP2 x86_64
Advanced Systems Management Module 12 x86_64

and in Product its create:
Advanced Systems Management Module 12 x86_64

and under repository:
1212 Advanced Systems Management Module 12 x86_64 SLE-Module-Adv-Systems-Management12-Debuginfo-Pool for sle-12-x86_64 yum Not Synced
0 Packages
0 Errata
0 Package Groups
0 Module Streams

1212 Advanced Systems Management Module 12 x86_64 SLE-Module-Adv-Systems-Management12-Debuginfo-Updates for sle-12-x86_64 	yum 	Not Synced 	

0 Packages
0 Errata
0 Package Groups
0 Module Streams

1212 Advanced Systems Management Module 12 x86_64 SLE-Module-Adv-Systems-Management12-Pool for sle-12-x86_64 	yum 	Not Synced

1212 Advanced Systems Management Module 12 x86_64 SLE-Module-Adv-Systems-Management12-Source-Pool for sle-12-x86_64 	yum 	Not Synced 	

0 Packages

1212 Advanced Systems Management Module 12 x86_64 SLE-Module-Adv-Systems-Management12-Updates for sle-12-x86_64 	yum 	Not Synced 	

0 Packages
0 Errata
0 Package Groups
0 Module Streams

And If I remove for example this repo 1212 Advanced Systems Management Module 12 x86_64 SLE-Module-Adv-Systems-Management12-Updates for sle-12-x86_64 how can I get back this repo?

I hope that I don’t have to remove Product and CW/activation keys…and then ad back from SUSE subscriptions…

Thanks
