  SAP Error Message:
  WRF_APC_INB122
  
  Text: Conflict for material &1: Two items refer to date &2 (shifted from &3 &4)
  
  Meaning / Cause:
  This error occurs in the Advanced Planning and Optimization (APO) module, specifically in the Demand Planning or Supply Network Planning area, when there is a conflict in the planning data for a material.
  
  The system has detected that two different planning items (such as demand or supply elements) are referring to the same date (&2), but one of them was originally scheduled for a different date (&3 &4) and has been shifted.
  This typically happens during the disaggregation or time bucket conversion process, where planning data is broken down from a higher-level time bucket (e.g., month) into lower-level time buckets (e.g., weeks or days).
  The conflict means that the system cannot assign two separate planning elements to the same date for the same material without causing inconsistency or overlap.
  
  
  Common Causes:
  
  Overlapping or duplicate planning elements for the same material and date.
  Incorrect or inconsistent time bucket settings in planning versions or planning areas.
  Errors in the disaggregation logic or rules that cause multiple items to be assigned to the same date.
  Manual changes or incorrect master data that cause date conflicts.
  Data inconsistencies after data transfer from ERP to APO or vice versa.
  
  
  Solution / How to Fix:
  
  
  Check Planning Data:
  
  Review the planning data for the material mentioned (&1) around the conflicting date (&2).
  Identify the two items that are causing the conflict.
  
  
  
  Analyze Time Buckets:
  
  Verify the time bucket settings in the planning version and planning area.
  Ensure that the disaggregation rules and time bucket conversions are correctly defined and consistent.
  
  
  
  Adjust Disaggregation Rules:
  
  If disaggregation is causing the conflict, adjust the rules or parameters to avoid overlapping assignments.
  For example, check the distribution keys or percentages used in disaggregation.
  
  
  
  Correct Master Data:
  
  Check the master data for the material, such as product location master, resource master, or calendar settings.
  Ensure that there are no inconsistencies that could cause date shifts.
  
  
  
  Data Consistency Checks:
  
  Run consistency checks or data validation reports in APO to identify and fix data issues.
  Use transaction /SAPAPO/SDP94 or /SAPAPO/SDP6 to analyze planning data.
  
  
  
  Re-run Planning:
  
  After corrections, re-run the planning or disaggregation process to see if the conflict is resolved.
  
  
  
  Consult SAP Notes:
  
  Check for any relevant SAP Notes that address this specific error message or related planning conflicts.
  
  
  
  
  Additional Information:
  
  This error is specific to SAP APO (Advanced Planning and Optimization) and is related to the internal planning logic.
  The placeholders in the message:
  
  &1 = Material number
  &2 = Date where conflict occurs
  &3 &4 = Original date from which the item was shifted
  
  
  Understanding the planning version, planning area, and time bucket configuration is crucial to resolving this issue.
  If the problem persists, consider involving SAP APO support or consulting with an APO expert.
  
  
  If you provide the exact context (e.g., transaction, planning version, or process step), I can help you with more tailored troubleshooting steps.
