I wonder why in Step 5 on First-party device IDs in the Platform Web SDK | Adobe Experience Platform uses FPID as primary identifier, given order of priority will only enabled ECID during new cookie identification of user. ie. Step 5 : should only have ECID = 678 instead of FPID = 012 being used as ...

@AtulChavan  any update on this one. 

Got it, but its not working for me. 1. I created a lookup class 2. uploaded data in to dataset however when i use the segmentation query i cant see the attributes. Note: only when using Search button, the results of look up attribute comes (without any data)

Can I use attributes in my Look-up class as part of my segmentation job? Currently am not seeing it available.

Proxy is appropriate approach. My experience in using at client location, is Proxy get timed-out , also keep look at performance.   Whilst, are you looking for un-authenticated offer disposition state to customers. In that case, you should rater use Adobe target and handle your use-case.

Is there a business case to export Dataset, because if you insert and export data to and from AEP, there is no transformation you are doing with in AEP. The right approach would be Dataset -- Segmentation -- Export to destination.

With in AEP, is there a way to export both Profile and Offers together. i.e I am looking for an output, where Example given below ProfileIDOfferIDOfferIDid1ofid1ofid2   Challenge, I see is Offers (Decision Object Repository - Personalized Offers ) dataset is missing my Pkey with-in Record Schema.   

Step 1: On day 1, I created Source data flow via Localfileupload Step 2: Uploaded .csv with 10 attributes into Dataset : Dataset1 Step 3: On day 2, I wanted to remove 2 attributes from 10   Thus question, could i do it ? 

The Segmentation API - Postman Collection is missing "Audiences" , is there plan to add it - https://github.com/adobe/experience-platform-postman-samples/tree/master/apis/experience-platform is missing https://developer.adobe.com/experience-platform-apis/references/segmentation/#tag/Audiences 

Good one bud
