Configuration and Permissions for new Angular based Web Portal (IT Shop)

Hello,

we are currently testing first steps towards the new Angular Web with version 9.1.1.
Now there seems to be still 2 points where we have not yet read properly from the documentation how to do the respective configuration/settings.

1) Where or how to configure the connection to the application server that provides the search index?

In the "old" WebDesigner Web" this was a setting either during the Installaiton on the Web Server or just about WebConfigFileEditor adjustable.

So far we have not been able to find the location for the new Angular Web.

2) It seems that new/additional permissions are needed to e.g. place an order - currently we get the following messages when trying to do so.- just some examples

ERROR --> VI.DB.DataAccess.NoPermissionToRunStatementException:  You do not have permission to run  'QER_FGIPWOOrderPerson'.

ERROR --> VI.DB.DataAccess.NoPermissionToRunStatementException: You do not have permission to run 'Webportal.QER_AccProductUsageSingle'.

Thanks a lot for your hints
