Hello All,
For a client we have use case to apply frequency as primary and recency as the fallback strategy. But with certain data limitation, recency could also give multiple values. So we have added another fallback strategy which is based on other attribute crosswalk winner. But as winner crosswalks are filtered at each level, final fallback strategy is not able to yield any value at all and shows no label in UI for those main attributes.
Example:
|
Crosswalk
|
LUD
|
First name
|
Person id
|
|
C1
|
1-12-2025
|
Lina
|
123
|
|
C2
|
2-12-2025
|
Luna
|
124
|
|
C3
|
2-12-2025
|
Lana
|
125
|
Consider above where survivorship strategy for person id is min value so 123 from C1 is the winner.
For first name , primary strategy is frequency which gives all three values , then recency give C2, C3 as winner crosswalk and to tie the break last fallback strategy is other attribute crosswalk winner (person id) . But as we can see, C1 was filtered out in first fallback strategy itself. Thus from last fallback strategy no value is coming in survivorship.
I want to use the unfiltered list in final fallback strategy. Is it possible to do or is there any other way to get only one value for attributes like first name and last name?
please note there is no scope to apply source priority and even with that this issue is reproducible.
