We are currently in the process of upgrading our SAP Portal from version 7.01 to version 7.30.
We have a perferctly working solution on version SAP Portal version 7.01 but am struggling to get the same solution to work for version 7.30.
Our SAP Portal system connects to the SAP backend systems (SAP-HR) and (SAP-FI)
Currently for the SAP Portal 7.01 version our solution is as follows:
 Header Variable Login has been configured on the SAP Portal.
 A junction mapping has been created in TAM for the SAP Portal, SAP HR and SAP FI.
 SSO between TAM and the SAP Portal works OK. This means that the Header Variable Login module has been configured correctly.
 The 1st tab on our SAP Portal is a BSP page containing information that comes from SAP HR. This currently works as follows:
----- TAM see's that a response has come from a different port number (reading an un-encoded URL)
----- TAM checks its mapping table and finds the apporpriate certificate to pass (along with the MYSAPSSO2 cookie)
----- TAM is then authenticated with SAP HR
We then configured the SAP Portal 7.30 in exactly the same manner, however it fails on step , unable to authenticate to SAP HR. The reason is that SAP Portal 7.30 is now using encoded URLs and TAM cannot read them.
Does anyone have a solution as to how TAM can authenticate with SAP backend systems using the new SAP Portal 7.30.
Thanks in advance for any advice/solutions offered.
