Do you want to see how to implement Role Playing Dimensions in Power BI, Click here and here. The most popular role-playing dimensions are DimDate and DimTime. Each linkage represents a single role or concept The relationships are defined by linking multiple foreign keys in the fact table to a single key in the dimension table.Ģ. You are linking a fact table to a dimension multiple times. When you link a dimension to a fact table several times for logically distinctive roles you’re using a role-playing dimension.ġ. Then I’ll express the way you can implement it in a SSAS tabular model. You have a second method to process the XMLA Script using a SSIS Analysis Service Execute DDL Task.First of all I’d like to explain what a Role-playing dimension actually means. Once you add the connection string and the XMLA variable set in the task you are good to go. You add the XMLA variable to the DDL command so that we pass in the generated XMLA script to the SSIS task. You simply make a connection to the SSAS Tabular instance via a connection string. Again you are using the original C# script to generate the XMLA Script. This method uses the SSIS task designed to execute XMLA scripts. Method 2: Analysis Service Execute DDL Task This is one way of processing the partition and a preferred preference if you feel comfortable with C# and Analysis Management Objects.Ĥ. Then you execute the send command and disconnect from the server.Ĭlnt.Connect(()) You instantiate the XmlaClient and connect with the Server This can be a pain in the butt to find but I found it on my machine under C:\windows\assembly\gac_msil\ and I picked the latest version of the .įinally you just add to the script we used to generate the XMLA script and execute it First you need to add the assembly to your script references so you can access the namespace. With the XMLA script above created you just need a way to execute it. The idea is that you use the StringBuilder library to design our same XMLA script but you add the all the variables in the right places and send it the XMLA variable for use in the next piece. Xmla.AppendLine("" + () + "") ĭts.Variables.Value = xmla.ToString() ĭts.Variables.Value = e.Message.ToString() ĭts.TaskResult = (int)ScriptResults.Success StringBuilder xmla = new StringBuilder() The following is a code snippet of the XMLA generated dynamically from the variables in a C# script and sent to the XMLA variable. You also want to add the XMLA variable to the ReadWriteVariables. In our script task you want to add the ServerID, DatabaseID, CubeID, PartitionID, Type, and MeasureGroupID to the ReadOnlyVariables. Create a C# script within SSIS that will allow you to generate the XMLA script and add variables so that it can be dynamic.Ĭreate several variables to allow us to make dynamic changes to the script because you may change databases, models, or partitions. This gives us the XMLA script that you can execute to process the partition selected. Select the Process Mode in our case you want to Process Full then select the Script option and choose the Script Action to New Query Window. Select the Partition you want and the Process button. To access the SSAS Tabular instance you right click on the table with the partition and select Partitions. Get the XMLA (XML for Analysis) from SQL Server Management Studio. The first thing I will mention is that you need to look at how the SSAS Tabular Partition is processed manually to see how you can use these 2 methods in SSIS.ġ.
