  The SAP error message /SAPAPO/FOT455 Extra WIP for soft up or down split is not available at unmapped RPs typically occurs in the context of Advanced Planning and Optimization (APO) when dealing with production planning and scheduling. This error indicates that there is an issue with the Work In Progress (WIP) management related to soft splits in the production process, particularly when the system is trying to allocate WIP to resources that are not properly mapped.
  Cause:
  
  Unmapped Resource Profiles (RPs): The error suggests that there are resource profiles in the planning process that are not mapped correctly. This can happen if the resource profiles used in the planning run do not correspond to the actual resources defined in the system.

  Data Consistency Issues: There may be inconsistencies in the master data or transactional data that affect how WIP is calculated and allocated.
  
  Solution:
  
  Check Resource Mapping: Ensure that all resource profiles used in the planning run are correctly mapped to the actual resources in the system. This may involve reviewing the configuration in the APO system and ensuring that all necessary mappings are in place.
  Review WIP Settings: Check the WIP settings in the APO configuration. Ensure that the settings for soft splits are correctly defined and that the system has the necessary WIP available for allocation.
  Validate Planning Version: Make sure that the planning version being used is correct and that it has the necessary data and settings. If needed, create a new planning version or adjust the existing one.
  Data Consistency Check: Perform a consistency check on the master data and transactional data to identify any discrepancies that may be causing the issue. This may involve checking the production orders, resource availability, and other related data.
