How To Fix WRF_CONS311 - Exploded structured material is ambiguous

SAP Error Message - Details

• Message type: E = Error

• Message class: WRF_CONS - Retail Fashion: Consignment Processing Stock Transfers

• Message number: 311

• Message text: Exploded structured material is ambiguous

What causes this issue?

Stock determination caused an error because the exploded structured
material is ambiguous.
The system can only update structured materials when the stock has been
determined uniquely.

System Response

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_CONS311 - Exploded structured material is ambiguous ?

  Certainly! Here's a detailed explanation for the SAP error message WRF_CONS311: Exploded structured material is ambiguous:
  
  Error Message
  WRF_CONS311: Exploded structured material is ambiguous
  
  Cause
  This error occurs during the explosion of a structured material (usually a configurable material or a material with variants) in SAP, typically in the context of:
  
  Sales Order processing
  Production Order creation
  BOM explosion
  Variant configuration
  
  The message indicates that the system cannot uniquely determine the correct exploded components of the structured material because:
  
  The configuration or selection criteria for the structured material are ambiguous or incomplete.
  There are multiple possible BOMs or configurations for the material that fit the given data.
  The system lacks sufficient characteristic values or variant conditions to resolve which variant or BOM to explode.
  The classification or variant configuration master data is inconsistent or incomplete.
  The selection conditions or dependencies in the variant configuration are not properly maintained, leading to multiple valid solutions.
  
  
  Solution
  To resolve the error, consider the following steps:
  
  
  Check Variant Configuration:
  
  Verify that the characteristics and values required to uniquely identify the variant are correctly entered.
  Ensure that the configuration profile and dependencies (preconditions, selection conditions) are properly maintained.
  Use transaction CU50 or CU51 to simulate the configuration and check for ambiguities.
  
  
  
  Review BOM and Master Data:
  
  Check the BOM(s) for the structured material to ensure that they are correctly maintained and assigned.
  Confirm that the BOM usage and validity dates are correct.
  Make sure that the BOMs are not overlapping in a way that causes ambiguity.
  
  
  
  Check Sales Order or Production Order Data:
  
  Ensure that all required configuration data (characteristics, variant conditions) are entered in the sales order or production order.
  If the structured material is configurable, make sure the configuration is complete and consistent.
  
  
  
  Use Configuration Trace:
  
  Use transaction CU50 or CU53 to trace the configuration process and identify where ambiguity arises.
  Analyze the trace to find missing or conflicting characteristic values.
  
  
  
  Adjust Dependencies:
  
  Review and correct dependencies (e.g., selection conditions, procedures) in the variant configuration to eliminate multiple valid solutions.
  
  
  
  Consult SAP Notes:
  
  Check for relevant SAP Notes that might address known issues with variant configuration or BOM explosion.
