You’ve changed something in your Tabular model and you’re facing an ugly “Error: Object reference not set to an instance of an object.” message, don’t rush. Just go to the table you’ve made some changes and click on “Partitions” button.
Then click “Refresh Preview” button and click OK.
All done!
You are working on a BI project that involves SSAS Tabular model. As you cannot process the model manually you need to develop a solution to process the model automatically. There are two scenarios here:
In this post I’m expressing easy ways to solve the problem based on the above scenarios.
Follow the steps below:

There is a group of users that are not intended to have direct read access to the database tables. There are some predefined database views that the users should be able to see the data through those views. In our case, the users shouldn’t be able to even see the tables in SSMS or through any applications that can connect to the database. Additionally, the users should be as restricted as possible. For instance, they shouldn’t even know what the source table names are. So SYS or INFORMATION_SCHEMA should not show any additional information.
The best possible way to achieve the goals is that we create a new database role and define the users as members of the new database role. We create a database role very easily though SSMS, but, if we have lots of views and we want to define accesses through the UI it would be a time consuming process. In addition, it increases the risk of human faults during setting up the configuration.
A very simple way is to use the following T-SQL script that will create a database role, it will also add the views as the role’s securables and it will grant the sufficient access rights so that any users that are members of the role be able to see the views. They’ll be also able to execute the views and see the results. You just need to make sure that the users are not members of some other roles that have overlap with the new role’s permissions.
In this post I’m explaining how you can deploy a developed SSIS project to several different environments. It might have happened to you that there are several environments that you need to deploy the SSIS projects to. Assume that you have DEV, QA, UAT and PROD environments. Some organisations might have even more environments. Also, there are many cases that you might have several PRODs that the SSIS packages should be deployed to all of them. So the scenario is that whenever you create a new SSIS project in DEV area or you may modify the existing projects, you need to deploy each SSIS project to QA for testing purposes. So, if you have 3 new SSIS projects or you’ve just modified 3 existing projects, you’ll need to deploy each project separately. It is the same story for QA guys after finishing the test cases and after the SSIS projects pass all the test cases. They’ll need to deploy all projects to UAT. Again it is the same story with UAT and PROD. It is getting harder when you need to deploy all the projects in several different PROD environments.
Using the solution below, you can easily deploy all SSIS projects from an environment to another environment or even several different environments.
