Data Prep - Mapping of ECID to freeform data (data.__adobe.analytics.eVarX)

[bjoern__koth]

Hi guys,

quick question about data prep mapping in a datastream. Is it actually only possible to map incoming data to the XDM schema, but not to enrich the free-form "data" object with additional information?

Example: I want to set a value to the "data.__adobe.analytics.eVarX" to the ECID?

When I try to map the ECID (screenshot), the autocomplete does not work, and hardcoded also does not work.

So, do you know why none of the contextual free-form data cannot be accessed in the mapping?

Alternatively, I think there is also no direct access to the ECID on AA processing rule side, correct?

Ideally, I would like to avoid using getIdentity for it due to its async nature.

alloy("getIdentity")

Any suggestions?

Cheers
