We are using SAP transactions from Portal using transaction iView.
In 46B all transactions were working fine from portal but after moving to ECC6, some transactions are giving error "maximum session reached".
I compared by running the same transaction from SAP GUI and found that at one place it is returning maximum session value as 6 but when it is being run from Portal this maximum session value is 1.
Function module for retrieving maximum session being used is TH_USER_INFO.
I believe somewhere maximum session value has to be changed in ITS.
I have seen the same issue in Portal forum but it is not answered there.
Looking forward for your valuable inputs.
