Receiving an error when attempting an ALM sync:
An internal error occurred while preparing the structural changes for synchronization. Reason for error: Parent line item is not a summary line item
If your line items have "Is Summary" checked in the development model, but incorrectly unchecked in your production model due to the issue described directly above, you are unable to subsequently sync if you do the following:
Give a formula to the line item which has a parent in the development model but incorrectly does not have a parent in the production model (due to "Is Summary" not being checked).
If you see this issue has occurred in your ALM models, for line items you have identified follow these steps:
In the dev model, remove or revert the formula change back to what it was originally
Sync to your production model
In the dev model, add the new formula back
Sync to your production model.
You will now want to take the steps to fix the "Is Summary" checkbox for these line items as described in the issue and workaround directly above
