Does anyone here know where I would find the table that defines the periods? I have looked everywhere but can not seem to find it, I did look at the Dimensions and there is a Period option there, but it does not appear to be where you actually define the periods.

Data exchange > Actions > Period Mapping

James specified two sections in the period mapping: default period mapping and source period mapping. In the case of NetSuite integration, the new periods must be added first in the default period mapping and then in the source period mapping.

@Todd Juenemann Did you manage to find and configure it? If not, please send your email so I would like to help. Michel,
