Internal Error when attempting ALM sync

This item has been identified as a known issue, please contact Support at support@anaplan.com if you encounter this.

A workaround is provided until the issue is officially fixed.


Sync fails with error:

"An internal error occurred while preparing the structural changes for synchronization. Please contact Anaplan Support."


The issue occurs if these changes are made in the same sync:

(simple list with hierarchy, i.e. child and parent items belong to same list, exists with a property already in the model)

  • list is made to be a numbered list,
  • item is added to list
  1. Make the list a non-numbered list,
  2. Create a revision and sync,
  3. Make list numbered,
  4. Create a revision and sync.
