RSA1 issue while creating datasource under sap folder

Hi Team,

In our BI system, Am going to create a new data source in RSA1 tcode in source systems under sap folder but it is not allowing me to create and giving the below error. Kindly look into this and revert me with appropriate steps to resolve the issue.

Btw, I have created the RFC connection b/w source system and target system.

Please enter a valid value for receiver type

Message no E0426

Entry with Key /BISYSCNLTXX/LS is to be inserted in the table EDPP1

The value /'USER'/'US' is not valid for a receiver of notifications.

Enter a valid value. Use the possible entries push button to display the values allowed.

Kindly respond this.

Thanks,

Pavan.
