• What is the cause and solution for SAP error message /SAPAPO/OM_TS301 - Negative value not permitted for this key figure ?

  The SAP error message /SAPAPO/OM_TS301 Negative value not permitted for this key figure typically occurs in the context of SAP Advanced Planning and Optimization (APO) when you are trying to enter or process a negative value for a key figure that does not allow it. This is common in scenarios involving planning, forecasting, or inventory management where certain key figures are expected to be non-negative (e.g., quantities, stock levels, etc.).
  Cause:
  
  Negative Input: The most straightforward cause is that a negative value is being entered for a key figure that is defined to only accept non-negative values.
  Data Transfer Issues: If data is being transferred from another system or module, there may be an issue with the data mapping or transformation that results in negative values being sent to the APO system.
  Configuration Settings: The key figure may be configured in such a way that it does not allow negative values. This is often the case for key figures related to inventory, sales, or production quantities.
  Calculation Errors: If the key figure is derived from calculations involving other key figures, an error in those calculations could lead to a negative result.
  
  Solution:
  
  Check Input Values: Review the values being entered for the key figure and ensure that they are non-negative. If you are entering data manually, correct any negative values.
  Review Data Transfer Processes: If the data is coming from another system, check the data transfer process to ensure that negative values are not being introduced. This may involve reviewing the mapping and transformation logic.
  Configuration Review: Check the configuration of the key figure in the APO system. If it is set to disallow negative values, you may need to adjust the configuration or use a different key figure that allows negative values if appropriate.
  Debug Calculations: If the key figure is calculated, review the underlying calculations to identify any errors that may be resulting in negative values. Ensure that all contributing key figures are also non-negative.
  Consult Documentation: Refer to SAP documentation or help resources for specific details about the key figure in question and its constraints.
  
  Related Information:
