Are the RTA's backward compatible?

34 Views

We want to upgrade our ECC 6.0 (SAPHR) system to EHP4 but leave our GRC 5.3 system at SP8. Our goal is to be able to upgrade the backend systems (ECC, BI, SRM, etc.) without GRC affecting when or what level we upgrade to. (We donu2019t want to hold off upgrading ECC just because of problems with GRC).

Question #1: Is GRC 5.3 SP8 compatible with ECC 6.0 EHP4?

Our Basis team tells me that when they upgrade ECC 6.0 to EHP4, that SP10 of GRC automatically gets pulled in (the RTA).

Question #2: Will GRC 5.3 SP8 (JAVA) work with an SP10 RTA? (In other words, is the RTA backward compatible?)

If your answer to #2 above is no, then:

Question #3: How do we NOT upgrade the RTA to SP10 when doing the EHP4 upgrade?

Is it just a matter of u201Cnot pickingu201D GRC as an add-on or is there a place where we can lower the support pack level for the RTAu2019s?

Thank you for your help,

Peggy
