How To Fix WRF_AT106 - Planned qty of distribution center was to be < 0; it will be set to zero

SAP Error Message - Details

• Message type: E = Error

• Message class: WRF_AT - Messages for Allocation Table RTFASH

• Message number: 106

• Message text: Planned qty of distribution center was to be < 0; it will be set to zero

What causes this issue?

The planned quantity of the distribution center &V2& in the allocation
table &V1& was to be less than zero (&V4&) during synchronization with
the purchase order &V3&. However, this is not permitted.

System Response

During synchronization, the system set the planned quantity of the
distribution center &V2& in the allocation table &V1& to zero. The
system was unable to synchronize the quantity change in the purchase
order fully in the allocation table.

How to fix this error?

Check the allocation table &V1& and adjust the quantities manually
(transaction WA02), so that the allocation table is complete.

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message WRF_AT106 - Planned qty of distribution center was to be < 0; it will be set to zero ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WRF_AT106: Planned qty of distribution center was to be < 0; it will be set to zero
  
  Cause:
  This warning message occurs during the planning or distribution process in SAP (often in modules like SAP APO, PPDS, or SCM) when the system calculates a planned quantity for a distribution center (DC) that results in a negative value. Since a planned quantity cannot logically be negative (you cannot plan to produce or distribute a negative amount), the system automatically resets this value to zero.
  The negative planned quantity can arise due to:
  
  Incorrect or inconsistent master data (e.g., stock levels, safety stock, or demand forecasts).
  Errors in demand or supply planning logic.
  Incorrect parameters or constraints in the planning run.
  Data inconsistencies between different planning levels or locations.
  Manual adjustments or overrides that lead to negative values.
  
  
  Solution:
  
  
  Check Master Data:
  
  Verify the stock levels, safety stock, reorder points, and other relevant master data for the distribution center.
  Ensure that demand forecasts and supply data are accurate and consistent.
  
  
  
  Review Planning Parameters:
  
  Check the planning run parameters and heuristics to ensure they are set correctly.
  Look for any constraints or rules that might cause the planned quantity to go negative.
  
  
  
  Analyze Demand and Supply:
  
  Investigate if there are any unusual demand spikes or supply shortages causing the negative calculation.
  Adjust forecasts or supply plans if necessary.
  
  
  
  Check for Manual Adjustments:
  
  Review any manual changes or overrides in the planning data that might have caused the negative quantity.
  
  
  
  Run Planning Again:
  
  After corrections, rerun the planning process to see if the warning persists.
  
  
  
  Consult SAP Notes:
  
  Check SAP Support Portal for any relevant SAP Notes or patches related to this message.
  
  
  
  
  Related Information:
  
  This message is a warning, not an error, meaning the system handles the situation by setting the planned quantity to zero to avoid inconsistencies.
  It is important to investigate the root cause to prevent potential planning inaccuracies.
  The message typically appears in logs or planning run results and can be used as a diagnostic indicator.
  Similar messages might appear in other planning or distribution scenarios where negative quantities are logically invalid.
