  The SAP error message PPEBAL126 indicates that there is an issue with the model mix in the production planning or capacity planning module. Specifically, it suggests that the model mix for a particular production order or planning scenario will be changed when you attempt to save your changes. This typically occurs in the context of production planning, where the system is trying to balance the production mix based on the available resources, capacities, or constraints.
