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

[Rut7]

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 ,

Yes, your understanding is correct..!!

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.

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.

@Rut7 ,

Also check if you are using the same field added in the initial query as a part of additional data for all these record types in the split activity.
