Upgrade to EHP6

Hi,

We have the following configuration with SAP

- SAP ERP 6.0 EHP4

SAP_APPL 604

EA-APPL 604

SAP_HR 604

EA-HR 604

- SAP BI 7.0 EHP1

- SAP PORTAL 7.0 EHP1

Additionally, we have Employee Self Service with the following components in Portal:

Software Components Vendor Name Version Provider Location Applied

BP_ERP5COM 1.41 SP6

BP_ERP5ESS 1.41 SP6

BP_ERP5HRA 1.41 SP6

BP_ERP5MSS 1.41 SP6

BP_ERP5PSS 1.0 SP17

BPERPTMS 1.40 SP6

SAP_ESS 603 SP6

SAP_MSS 600 SP6

SAP_PSS 600 SP6

SAPPCUI_GP 603

Now, we have to upgrade to EHP6 in ECC. The question is, if we upgrade ECC to EHP6, we have to upgrade SAP BI and SAP PORTAL also?

What about ESS/MSS... we have to upgrade also? What is the versión compatible with SAP_HR 606?

Thank's for your help.

Best Regards

Juan Carlos BArraza
