While doing submit accounts in POS giving error ‘Server not configured for RPC'

Solution:
Run the following query using query analyzer (replace ‘myserver’ with your server name):

exec sp_serveroption @server='myserver', @optname='rpc', @optvalue='true'
go
exec sp_serveroption @server='myserver', @optname='rpc out', @optvalue='true'
go

Note: The above error is related to SQL Server configuration settings and not related to the application. (RPC is Remote Procedure Call).
