We are running SAP ECC 6.0 EHP4 as backend system with SAP Enterprise Portal Netweaver 7.0 EHP1.
We are using Win7 as operating system, IE8 browser support and SAP GUI 7.20 patch level 5.
We plan to upgrade browser support to IE9. As describe in PAM we need to upgrade SAP EP to SPS09.
But, will SAP EP SPS level update affect the BP and XSS package level so that we need to deploy them in another level?
We also have SAP GUI for Windows function, do we need to update the SAP GUI patch level?
Thanks in advance.
