Summary:

Content (required):

Hi all

Can someone please point me to documented steps to load ERP metadata directly to Planning - not via file load?

I can't find the correct section in the Data management Cloud and when we to use the Data Exchange, the location is always empty even though we created in DM. I think we are missing a step, but not sure which one.

Thank you
