Hi @Pradeep-Jaiswal    I think it depends on your design whether to use a single or multiple connections. But one thing to consider is on license usage. As far as I know, CJA license depends on the number of processed records in all the connections. So the multiple connections approach may end up wi...

Hi @Pradeep-Jaiswal    You can just create 1 schema, and include the OOTB AA Experience field group and add custom schema that fits your business model for CJA reporting.   In the AA connector, it will automatically populate data from the AA Report Suite to the AA Experience field group fields, and ...

Hi @Pradeep-Jaiswal    No worries on the "timing mismatch", it's based on the timestamp of the hit instead of ingestion time.   The latency of the AA source connector to AEP is not 15mins, please refer to below link,   https://experienceleague.adobe.com/en/docs/experience-platform/sources/connectors...

Hi @jlasso71    That's right, and hope it works well.   You may have to merge some other fields with simialr situation where differnet schema fields are used in connector and SDK. And some of them could be more challenging as their lookup values are different e.g. Device Name, Province Name.   Thank...

Hi @jlasso71    Use the Merge function, see below.     Thanks, John  

Hi @reddy_y-11    If it's a new CJA implementation, don't think it's needed to leverage those AA field group, the beauty of CJA is to design a XDM schema which fits your business model instead of binding to eVars in AA.   There are still some standard field groups that is useful, e.g. ProductListIte...

Hi @reddy_y-11    Why would you use the AA field group and eVars etc if you are implementing CJA? Based on my experience the AA field group is for 1) Send data to AA using Web SDK and 2) send data from AA report suite to CJA using Adobe Source Connector with custom schema. Or this is an existing Web...

Hi @jlasso71    In your CJA data view, e.g. device type, do you see below schema fields?   _globallookupscjaapac.deviceType   device.type   Since my implementation have both AA connector and Web SDK, I forgot which field is populated by connector or SDK, but I believe it should be available out of t...

Hi @_Paul_S    Depending on your design, you can also create multiple data stream and use data stream override in Adobe Launch.   https://experienceleaguecommunities.adobe.com/t5/adobe-experience-platform-data/using-dynamic-datastream-id-value-in-websdk-extension/m-p/705232#M7274   Thanks, John  

Hi @Ricardo-33    If your scenario is about totally separate devices, e.g. same person using your app on iPhone and also access the web site on the desktop, the solution would be cross device visitor stitching where the journey of the same person authenticated with say user_12345 on different device...
