Loadrunner-Error -26628: HTTP Status-Code

Hi,
I'm getting an error while replaying the SAP application using SAP protocol.
URL - HTTP
LoadRunner version - 11.52
 
Steps followed -
Recorded script using  SAPWeb    protocol
 
 
I'm able to record the script, but unable to replay - getting error message "Error -26628: HTTP Status-Code=403 (Forbidden) for "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx/;sap-ext-sid=MlleCo3CKKfNxUNIZFMwiw--ZPpjb_f4qQdNQRBrPpKQsg--?sap-contextid=SID%3aANON%3asapbatch02_WE3_14%3aPmbxySI88dBNeavpYpD2RtGMj2L1lCM7IZJ4-brU-NEW"
 
 
Prompt response would be highly appreciated.
 
Thanks and Regards
