Level 2 Sprint 2 Module to Module Aligning Dimensions Mapping
In one of the Sprint 2 activities, we need to reference data from one Module to another. To do this you must align the dimensionality of the Source Module to the Target Module. However the List dimension in the Source Module is a Parent of the corresponding dimension in the Target Module, requiring us to use an intermediary (SYS) module to align the source to the target.
How would you do that?
I have tried multiple variation of LOOKUP, and LOOKUP & SELECT however I continue to receive error messages.
When you are trying to align or match dimensions between 2 modules If the List in the Target module is a Parent of the list in the Source module then you don't need to use any mapping to align based on this Parent-child dimension.
Here is why...In the illustration below it shows the Parent data is already included in the Source list, so when the Target tries to retrieve data from the Source it'll find the list item to match to. I hope the image explains better than my words 😀
Please note that the reverse is not correct. If the Source had the Parent and the Target had the child lists, then you will need an intermediary mapping
