• Message number: 105

• Message text: Planned qty of the alloc. table item was to be < 0; it will be set to 0

What causes this issue?

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

System Response

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

• What is the cause and solution for SAP error message WRF_AT105 - Planned qty of the alloc. table item was to be < 0; it will be set to 0 ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WRF_AT105: Planned qty of the alloc. table item was to be < 0; it will be set to 0
  
  Cause:
  This warning message occurs during the planning or allocation process in SAP (often in modules like PP, SD, or WM) when the system calculates a planned quantity for an allocation table item that results in a negative value. Since planned quantities cannot be negative, the system automatically resets this value to zero.
  Typical reasons include:
  
  Incorrect or inconsistent master data (e.g., BOM, routing, or allocation tables).
  Errors in demand or supply quantities leading to negative planned quantities.
  Incorrect parameter settings or formulas in allocation or planning procedures.
  Data inconsistencies or rounding issues during calculation.
  Over-allocation or over-consumption scenarios where the system tries to allocate more than available.
  
  
  Solution:
  
  
  Check Master Data:
  
  Verify the allocation table entries, BOMs, routings, and related master data for correctness.
  Ensure that no negative quantities are defined or implied in these data sets.
  
  
  
  Review Planning Parameters:
  
  Check the planning strategy and parameters to ensure they are set correctly.
  Look for any custom formulas or user exits that might cause negative calculations.
  
  
  
  Analyze Demand and Supply:
  
  Review the demand and supply quantities feeding into the planning run.
  Identify if any demand or supply values are causing the negative planned quantity.
  
  
  
  Adjust or Correct Data:
  
  Correct any identified inconsistencies or errors in the data.
  If rounding issues are suspected, adjust decimal places or rounding rules.
  
  
  
  Check for SAP Notes:
  
  Search for relevant SAP Notes that might address known issues related to this message.
  
  
  
  Monitor the Impact:
  
  Since the system sets negative planned quantities to zero, verify if this impacts your planning results or inventory levels.
  Adjust planning logic if necessary to avoid zeroing out important quantities.
  
  
  
  
  Related Information:
  
  This message is a warning, not an error, so the planning run continues but with adjusted quantities.
  It is important to investigate the root cause to avoid incorrect planning results.
  The message is often seen in SAP PP (Production Planning) or SAP SD (Sales and Distribution) during allocation or planning runs.
  Check transaction logs or planning run logs for more detailed information on where the negative quantity originated.
  If custom enhancements or user exits are involved in planning, review their logic for potential causes.
