I have installed POS and Retail headquarters. am trying to connect to Store server from POS register i.e. Online POS. while trying to open the POS client the following error is coming.
“Unable to start the application. The Application will shutdown”
For me, it said that access to the database could not be granted.
I had tried to follow the installation guide to the letter, but it suggests creating a SQL-server login with the same name as the POS-user group.
After creating this login using Windows authentication instead, (applying the db_datawriter, db_datareader to the respective databases and dbo-schema), the user was allowed login.
