MQ118 - Details

• The SAP error message "MQ118 Active package & is a forecast package; activation not possible" typically occurs in the context of SAP Integrated Business Planning (IBP) or SAP Advanced Planning and Optimization (APO) when there is an attempt to activate a planning package that is designated as a forecast package. 
  
  Cause:
  
  Forecast Package: The package you are trying to activate is a forecast package, which is not meant to be activated in the same way as other types of planning packages. Forecast packages are typically used for generating forecasts and are not intended for activation in the same manner as standard planning packages.
  Incorrect Activation Attempt: The error may arise if there is an attempt to activate a package that is already active or if the system is trying to activate a package that is not designed for activation.
  
  
  Solution:
  
  Check Package Type: Verify the type of the package you are trying to activate.
