Hi Sreeni,
this behaviour is related to the GUID conversion exit handeled by SE16 (and SE16N on ECC). This behaviour can't also be changed. Due to this restriction with GUID search of DPR*-tables in SE16 or SE16N SAP has released a GUID-analyze programm with forward-navigation.
Have a look to DPR_GUID_ANALYZE (via SE38/SA38). It has the advantage, that is searches Projectmanagement and Portfoliomanagement tabels and provides an overview of entries found in tables. The GUIDs of the output list are clickable in terms of forward-navigation.
The report also has a big advantage, as it supports customer tables via pattern (e.g. 'Z*') in the selection screen. Additional patterns can be added easily.
It is an outcome of the great idea of Customer Connection Programm for PPM (released in cycle 1 and fine-tuned in cycle 2).

Peter
