FDMEE Excel budget upload template not importing

Hello!

We are upgrading from FDM to FDMEE and are trying to update our old budget upload Excel templates for the new FDMEE. We are currently on FDMEE 11.1.2.4.200.012.

In the old FDM, our template looked like this for 12 periods:

We tried to replicate it in the same manner for the upgraded app using our updated dimensions:

Both are in .xls format. The data load rule I’m using looks like this:

When I try to load the multiperiod by using execute using the following options, it gives me an error (Rule execution did not complete successfully) that it failed to import data for all 12 periods. In the data load mapping, we have like mapping * to * for all the dimensions. We also looked in the old FDM for any scripting that may have been built for this template, but there was none. Is there some sort of documentation that exists that shows how to upload budget to FDMEE? We searched and could not find it.
