| free              | Free           | Allows you to create small proof-of-concept development projects. Also can be used for the piloting of a remote ABAP test cockpit scenario against on-premise systems in the Custom Code Migration app. The instance will be stopped each night automatically and needs to be started again via the Landscape Portal. Only community support is available for free tier service plans and these are not subject to SLAs.                                                                     |
| standard          | Standard       | Allows you to create projects for development, test, and productive ABAP systems. The minimum system size is 2 HANACompute Units and 1 ABAP Compute Unit. It is mandatory to assign a combination of three entitle- ment service plans: ABAP Compute Unit, HANACompute Unit, and either the Free, Standard, or SaaS OEMplan.                                                                                                                                                                 |
| abap_compute_unit | Standard       | Allows you to configure runtime memory, which refers to volatile memory used during the execution of applications. This memory provides fast read and write access but loses all data when the system is restarted or shut down. The metric measures the amount of runtime memory used in 16 GBblocks on an hourly basis. It is mandatory to assign a combination of three entitle- ment service plans: ABAP Compute Unit, HANACompute Unit, and either the Free, Standard, or SaaS OEMplan. |
| hana_compute_unit | Standard       | Allows you to configure persistent memory, which refers to storage that retains data even after the system is restarted or shut down. The metric measures the amount of persis- tent storage used in 16 GBblocks on an hourly basis. It is mandatory to assign a combination of three entitle- ment service plans: ABAP Compute Unit, HANACompute Unit, and either the Free, Standard, or SaaS OEMplan.                                                                                      |
| saas_oem          | SaaSOEM        | Allows you to create projects for ABAP systems to run multitenancy SaaS applications. The minimum system size is 2 HANACompute Units and 1 ABAP Compute Unit. It is mandatory to assign a combination of three entitle- ment service plans: ABAP Compute Unit, HANACompute Unit, and either the Free, Standard, or SaaS OEMplan.                                                                                                                                                             |
