XML configuration file does not show entry for PI_BASIS for PREPARE

Hello SAP Gurus,

We are doing ECC 6.0 SR3 upgrade including EHP3 SP3

We generated XML configuration file for EHP3 from MOPZ

But during XML file does not contains any information for PI_BASIS target level or source level

current level is 2006_1_620

We tried that XML file in PREPARE during EHP_INCURSION phase

but failed all time.

Let me know what we have to generate XML file with proper information including PI_BASIS

Even PI_BASIS not appearing in MOPZ list for selection, its surprising for us.

Any idea/direction would be highly appreciated.

Thanks,

Amit Lal
