• What is the cause and solution for SAP error message /SAPAPO/ATP_BOP091 - Stock or receipt can only be partially used to cover requirements ?

  The SAP error message /SAPAPO/ATP_BOP091 indicates that there is an issue with the availability of stock or receipts in the Advanced Planning and Optimization (APO) module, specifically related to the Available-to-Promise (ATP) check. This error typically arises when the system determines that the available stock or receipts can only partially fulfill the requirements for a specific demand.
  Cause:
  
  Insufficient Stock: The available stock or receipts are not enough to cover the entire demand. This can happen if the demand exceeds the available quantity.
  Allocation Issues: There may be allocation strategies in place that restrict the use of stock for certain requirements, leading to partial fulfillment.
  Multiple Requirements: If there are multiple requirements for the same stock, the system may only be able to allocate a portion of the stock to each requirement.
  Time-Phased Requirements: If the requirements are time-phased, the stock may not be available at the right time to cover the entire demand.
  Batch Management: If batch management is enabled, the system may only be able to allocate specific batches that meet certain criteria, leading to partial usage.
  
  Solution:
  
  Check Stock Levels: Review the available stock and receipts to ensure that they are sufficient to meet the demand. If not, consider increasing stock levels through procurement or production.
  Review Allocation Strategies: Examine the allocation strategies configured in the system. Adjust them if necessary to allow for better stock utilization.
  Adjust Requirements: If possible, adjust the requirements to align better with the available stock. This could involve rescheduling orders or changing delivery dates.
  Batch Management Review: If batch management is in use, ensure that the batches available can cover the requirements. You may need to adjust batch selection criteria.
  Use of Safety Stock: Consider implementing safety stock levels to ensure that there is always a buffer available to cover unexpected demand spikes.
  Consult ATP Settings: Review the ATP settings in the system to ensure they are configured correctly for your business processes.
