ALM - Failed sync when deleting a Line Item Subset

This item has been identified as an outstanding known issue.  A workaround has been provided until the issue is officially fixed. 


You receive an error when attempting to sync if you have deleted a Line Item Subset and changed the format of a Line Item which was previously in the deleted Line Item Subset (eg from Number to Text) within the same revision


An internal error occurred while preparing the structural changes for synchronization. Reason for error: Not permitted to change format of line item m.a to BOOLEAN because it is included in line item subset 'F7B15147C7D843F89717348A3B2CE15A' Only line items with NUMBER format can be included in a line item subset.


To workaround this, change the Line Item format back to Number, sync to your production model, change the format to what you want (eg Boolean), sync to your production model.


If this workaround is not suitable in your use case, please contact Support at
