I'm not sure what you mean by application layer. You can create a scan request packet just like you create an advertising packet and put any data in it as long as the stack can encode it properly.

Here Application layer means user code.My question is with respect to Central. The central runs a active scanner so the Advertising packets are received and SCAN_REQUEST is sent and SCAN_RESPONSE is received from peripheral and then the data is sent to the application. Can we modify SCAN_REQUEST packet sent by central or it is totally handled by softdevice.
Sorry for answering this late, you might have already figured it out.
SCAN_REQ PDU is set completely by softdevice depending on previous settings of scanner device address and the advertiser device address from which scanner wants to get more data.
