Hi Dipesh
Two things are missed I guess.
1. Prakhar already mentioned where is SAP Layer (SAP-> 700) , and check the properties of layers.
2, Had you link the domain of transports from solman to PEC?
Also have you create the cts project in PEC development system?
How are your client specific import options etc.?
Please check below link for domain linking activities.
