• What is the cause and solution for SAP error message /PLMB/BA_RCP_MODEL101 - Simulated rows must not be negative ?

  The SAP error message /PLMB/BA_RCP_MODEL101: Simulated rows must not be negative typically occurs in the context of SAP's Advanced Planning and Optimization (APO) or similar modules where simulation or planning models are being executed. This error indicates that there is an issue with the data being processed, specifically that the number of simulated rows is being calculated as a negative value, which is not valid.
  Causes:
  
  Data Input Issues: The input data for the simulation may contain negative values or incorrect configurations that lead to a negative count of simulated rows.
  Configuration Errors: There may be misconfigurations in the planning model or parameters that dictate how simulations are run.
  Model Constraints: Constraints defined in the planning model may not be set up correctly, leading to an invalid state where the simulation cannot proceed.
  Versioning Issues: If there are multiple versions of the planning model, there may be inconsistencies between them that lead to this error.
  
  Solutions:
  
  Check Input Data: Review the input data for the simulation to ensure that all values are valid and that there are no negative entries where they shouldn't be.
  Review Model Configuration: Go through the configuration settings of the planning model to ensure that all parameters are set correctly and that there are no conflicting settings.
  Validate Constraints: Check the constraints defined in the model to ensure they are logical and do not lead to negative simulated rows.
  Debugging: If possible, run the simulation in a debug mode to identify the exact point where the negative value is being generated.
  Consult Documentation: Refer to SAP documentation or notes related to the specific module you are using for any known issues or patches that may address this error.
  Contact SAP Support: If the issue persists after checking the above, consider reaching out to SAP support for assistance, providing them with detailed information about the error and the context in which it occurs.
