I have a unique use-case that I've been trying to solve. We have a public facing website, where we capture an identifier for a user through an email that contains the user ID in the link. When a user comes to the site through the link, we can capture all future data as being tied to the user through the eVar, but we are unable to tie it to the user in the past if the date range doesn't include when it was set for the user.
Is there a way to insert data into an eVar that was previously unspecified in the past that has now been identified? I've looked at the Data Repair API, and it seems like when it's out of beta could assist here, but I wanted to confirm I wasn't overlooking a simpler approach in the interim.
Data Sources has a specific template/format via which the data is uploaded. But if you try uploading again via Full Processing Data Sources, we might see double metric/instances. If the objective is to delete existing data and then re-upload the correct data, our Engineering Services team is the option here (via your CSM), or we can wait for the feature to be available in Data Repair API.
