File-to-RFC scenario in PI 7.1

I am doing a set up for the File-to-RFc scenario.  Testing works fine in Message mapping and Test configuration.

The file is picked from sender side and also able to view the data in SXMB_MONI.

I am getting the following error in C.C monitoring of receiver:

Receiver channel 'CC_FILE2RFC1_RECEIVER' for party '', service 'DEC' (internal name 'RfcClient[CC_FILE2RFC1_RECEIVER]')

Client data: {jco.client.lang=EN, jco.client.snc_mode=0, jco.client.client=110, jco.client.passwd=******, jco.webas.ignore_jdsr_error=1, jco.client.user=****, jco.client.sysnr=02, jco.client.ashost=*****}

Repository data: {jco.client.lang=EN, jco.client.snc_mode=0, jco.client.client=110, jco.client.passwd=******, jco.webas.ignore_jdsr_error=1, jco.client.user=****, jco.client.sysnr=02, jco.client.ashost=****}

Current pool size: 0, maximum pool size : 1

And the following error in SXMB_MONI:
