How To Fix WRF_APC838 - Distributed items could not be created, resulting quantities too small

SAP Error Message - Details

• Message type: E = Error

• Message class: WRF_APC - Messages for Operational Assortment Planning and Control

• Message number: 838

• Message text: Distributed items could not be created, resulting quantities too small

What causes this issue?

The system attempted to distribute the currently planned putaway
quantities; however, the calculation resulted in quantities that were
equal to zero, most probably due to rounding.

System Response

The system could not create distributed purchasing list items.

How to fix this error?

If you want to distribute your putaway quantities, you need to plan
larger putaway quantities.

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_APC838 - Distributed items could not be created, resulting quantities too small ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WRF_APC838 - Distributed items could not be created, resulting quantities too small
  
  Cause:
  This error typically occurs in the context of Production Planning and Detailed Scheduling (PP/DS) or Advanced Planning and Optimization (APO) when the system tries to distribute a production order or planned order quantity into smaller lot sizes or components, but the resulting quantities after distribution are too small to be processed or are below the minimum lot size defined in the system.
  More specifically:
  
  The system attempts to split or distribute a planned quantity into multiple items or lots.
  The resulting distributed quantities fall below the minimum lot size or rounding limits.
  This leads to the system being unable to create the distributed items because the quantities are not feasible for production or procurement.
  
  
  Typical Scenarios:
  
  Lot size settings (e.g., minimum lot size, rounding values) in the material master or production version cause the distributed quantities to be too small.
  The planned order quantity is very small or not aligned with the lot size settings.
  Rounding rules in the system cause the distributed quantities to be rounded down to zero or an invalid quantity.
  Incorrect or overly restrictive settings in the planning parameters.
  
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check Lot Size Settings:
  
  Go to the material master (MM02) ? MRP 1 or MRP 2 views.
  Verify the Lot Size indicator (e.g., Fixed lot size, Lot-for-lot, Rounding, Minimum lot size).
  Ensure that the minimum lot size and rounding values are set appropriately and not too large compared to the planned quantities.
  
  
  
  Adjust Planned Order Quantity:
  
  Increase the planned order quantity so that when distributed, the resulting quantities are above the minimum lot size.
  Avoid very small planned order quantities that cannot be split further.
  
  
  
  Review Production Version and BOM:
  
  Check the production version and Bill of Materials (BOM) for any constraints or minimum quantities.
  Ensure that component quantities and lot sizes are consistent.
  
  
  
  Check Rounding Rules:
  
  Review rounding rules in the material master or planning parameters.
  Adjust rounding values to prevent quantities from being rounded down to zero.
  
  
  
  Adjust Planning Parameters:
  
  In APO or PP/DS, review the planning parameters and heuristics that control distribution and lot sizing.
  Modify parameters to allow smaller lot sizes if feasible.
  
  
  
  Debug or Analyze Logs:
  
  Use transaction codes like /SAPAPO/SDP94 (PP/DS) or check the detailed error logs to identify exactly which item or quantity is causing the problem.

  Summary:
  The error WRF_APC838 arises because the system cannot create distributed items due to resulting quantities being too small, often caused by lot size and rounding settings. Adjusting lot size parameters, increasing planned order quantities, and reviewing rounding rules typically resolves the issue.
