• What is the cause and solution for SAP error message /SAPAPO/CDPSOPT203 - Resource constraint has a negative value ?

  The SAP error message /SAPAPO/CDPSOPT203 Resource constraint has a negative value typically occurs in the context of Advanced Planning and Optimization (APO) when there is an issue with the resource constraints defined in the planning environment. This error indicates that one or more resource constraints have been set to a negative value, which is not valid in the context of resource planning.
  Cause:
  
  Negative Resource Values: The most common cause of this error is that the resource capacity or availability has been defined with a negative value in the system. This could happen due to incorrect data entry or configuration.
  Master Data Issues: There may be issues with the master data related to resources, such as incorrect settings in the resource master data or planning book.
  Data Migration Issues: If data has been migrated from another system, there may have been errors during the migration process that resulted in negative values being introduced.
  Planning Version Issues: The planning version being used may have constraints that are not properly defined or have been altered incorrectly.
  
  Solution:
  
  Check Resource Master Data: Review the resource master data in the APO system to ensure that all resource capacities and constraints are set to valid (non-negative) values. You can do this by navigating to the resource master data transaction and checking the relevant fields.
  Review Planning Books: Check the planning books and key figures to ensure that there are no negative values defined for the resource constraints.
  Adjust Constraints: If you find any negative values, correct them to appropriate positive values that reflect the actual capacity or constraints of the resources.
  Data Validation: If the error occurred after a data migration, validate the data to ensure that all values are correct and consistent with the business logic.
  Check Planning Versions: Ensure that the planning version you are using is correctly set up and does not contain any erroneous constraints.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like /SAPAPO/RRP3 (Product View) or /SAPAPO/RRP4 (Resource View) to analyze the resource constraints and their values.
