Summary:

Default Location not populated on Org in Manage Supply Network Model after data collection. Impact?

Content (required):

The default location is populated for some organizations and not populated for some orgs in Manage Supply Network Model after data collection is run. We are having data collection from ERP cloud source.

In our case, this issue is seen for Contract Manufacturing(CM) Organizations but it could occur for non-CM orgs as well.

My question is what is impact of missing default location? Will it cause a big problem in terms of functionality in Supply Planning?
