Is it possible to pull in the columns based on an iterative basis? Like using the nth value?

Use Case: want to unify 90% of a pref. center across all BUs (26) but allow for BUs to have their own preferences (some will have 5 publication options some will have up to 10..etc. So, inherently, within the cloudpage, it would need to have a dynamic portion based on pref. center data extension at the BU level.

You should be able to achieve your multi-business unit pref center model by using the SSJS WSProxy module. The WSProxy.prototype.setClientId({ ... }) method allows you to interact with child business units by specifying their ClientID/MID.

  • You'll probably need to send the MID through the query string; the personalization string in the pref center's context will probably be the parent BU's, but I haven't tested. Commented May 17, 2019 at 19:34
