## Exact use case and how "Enable overlapping of output population" works in split activity of ACC?

Level 4

Hi All,

I'm trying to understand "Enable overlapping of output population in split activity's" exact working (Including input/output parameters) and use cases, could anyone point me to good references or explain the working?

Thank you,

Hi @Rut7 ,

Consider the below use case,

You have 6 recipients in query output

 recipient Country Gender A INDIA MALE B INDIA MALE C INDIA MALE D INDIA FEMALE E US FEMALE F US FEMALE

Here 4 recipients belongs to INIDA and 2 belongs to US

and 3 are male, 3 are female recipients

If you have split with 2 subsets.

Subset-1 : country = INDIA

subset-2: Gender = Male

If you don't enable 'overlapping of output population', in subset-1 output will be 4, and subset-2 output will be 0. Though you have 3 male records, but those records now went into subset-1 transition as they belongs to subset-1 criteria as well (country as INDIA). So those records wont come in subset-2 transition.

But if the campaign scenario is that you want output like, 4 records in subset-1 (India) and 3 records in subset-2 (Male), then you want to enable 'overlapping of output population'.

Hope this example clear your question

Thanks @ParthaSarathy .

By above you mean:

if "overlapping of output population" is enabled then,

subset 1 and subset 2 receive all inbound records.

If not enabled then,

All records received and segmented by subset 1 are not received by other subsets configured. In short Other segments receieve remainder records.

Is this correct understanding?

Hi @Rut7 ,

By definition, The Enable overlapping of outbound populations option defines how to manage profiles belonging to several segments:

• When the option is not enabled, the Segmentation activity checks a profile is not present in several output transitions, even if this profile meets the criteria of several subsets.
• When the option is enabled, the profiles can be found in several subsets if they meet their filter criteria.

Level 1

Adding to what Partha has mentioned in his answer, the split activity filters the inbound population sequentially, so in case you define the segmentation criteria to get gender='Male' first followed by country='INDIA' with enable overlapping unchecked, you will end up with 3 records in transition for Male gender and 1 record in transition for country is INDIA.

Whereas, if country='INDIA' criteria is defined first followed by gender criteria with enable overlapping unchecked, you will end up with 4 records in country check transition and 0 records in gender transition.

So to make sure that you get the correct records for this use case, you would need to check the enable overlapping checkbox. Hope this helps.
