With TM1 it is also very common to work with various other attributes. But when you create a package with framework manager you can choose what alias you want to show in reports.
For example, the modeller may use the coalesce function to substitute a null for a zero. The bold text in the SQL shows this pushed into the sub-query, whereas the null substitution is needed within the parent query after the stitch.
At the sub-query level there are no nulls. The nulls only occur after the stitch. There are documented methods around this issue. Within Report Studio or Business Insight Advanced, the simple Sales Quantity business report studio filter Returns Quantity calculation can be replaced with something that checks for nulls as shown below.
If the calculation is not written in a way that forces it to happen after the stitch, then we are back in the previous position.
In this case, the coalesce function includes facts from each fact table. In order for this calculation to be possible, it must be applied after both fact sub-queries have been returned. The coalesce first evaluates the variance calculation we are interested in.
If it is null, then it will attempt to return Sales Quantity.
If that is null, then a negative instance of Returns Quantity is returned. And finally, if that is null, then it returns a 0. However, for Query Studio users there is no easy way to get a simple variance working for multiple fact tables. The only way to do this is to put the null checking variance calculation using the coalesce function in the Framework Manager model.
Query Studio users can then use the appropriate variance calculation.
This does mean that all variances between facts that are needed by Query Studio users will have to be created by the Framework Manager modeller. Illustration 4 shows an example of a Framework Manager model using a stand-alone calculation called Sales Return Variance located in a Calcs folder under the Sales namespace.
The definition is the same coalesce statement shown earlier. Framework Manager model displaying a stand-alone Sales Returns Variance calculation Depending on the nature of your calculation and the desired results, you may need to ensure that the Regular Aggregate property for the stand-alone calculation in the model is set to Calculated.
This property aggregates the values first and then performs the calculation instead of calculating the details first and then aggregating the results.
This order of operations is only possible with stand-alone calculations in Framework Manager or calculations created in the studios. It does not apply to calculations embedded in query subjects. Illustration 5 shows that the model calculation works when a Sales Quantity value is null.
