• What is the cause and solution for SAP error message /SAPAPO/PP_OPTIMIZER276 - LP is unbounded ?

  The SAP error message /SAPAPO/PP_OPTIMIZER276 LP is unbounded typically occurs in the context of the SAP Advanced Planning and Optimization (APO) module, particularly when using the optimizer for production planning and scheduling. This error indicates that the linear programming (LP) model being solved does not have a bounded solution, meaning that the solution can increase indefinitely without reaching a maximum or minimum value.
  Causes:
  
  Model Formulation Issues: The LP model may be incorrectly formulated, leading to a situation where there are no constraints to limit the solution space.
  Missing Constraints: Essential constraints that should limit the decision variables may be missing or incorrectly defined.
  Infeasible Data: Input data may be inconsistent or infeasible, leading to an unbounded solution.
  Infinite Resources: If the model assumes infinite resources (e.g., unlimited capacity), it can lead to unbounded solutions.
  Incorrect Variable Definitions: Decision variables may not have appropriate bounds defined (e.g., they are allowed to take negative values when they
