How To Fix WRF_APC055 - Generic material &2 does not have all variants of generic material &1

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 055

• Message text: Generic material &2 does not have all variants of generic material &1

What causes this issue?

Generic material &V2& does not have all variants used by the dependent
prepacks of generic material &V1&, therefore you cannot copy the
dependent prepacks from generic material &V1& to generic material &V2&.

System Response

The prepack materials are not copied.

How to fix this error?

First add the missing variants to generic material &V2&, then copy the
prepack materials.

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_APC055 - Generic material &2 does not have all variants of generic material &1 ?

  Certainly! Here's a detailed explanation of the SAP error message:
  
  SAP Error Message:
  WRF_APC055: Generic material &2 does not have all variants of generic material &1
  
  Meaning / Cause:
  This error occurs in the context of Variant Configuration in SAP, specifically when working with Generic Materials and their Variants in the Advanced Planning and Optimization (APO) or ERP system.
  
  Generic Material: A material that represents a product with multiple variants (e.g., a T-shirt available in different sizes and colors).
  Variant: A specific version of the generic material with particular characteristics (e.g., T-shirt, size M, color red).
  
  The error message indicates that a generic material (represented by &2) is expected to have all variants of another generic material (represented by &1), but this is not the case. In other words, the system expects that the generic material &2 should include all the variants that exist for generic material &1, but some variants are missing.
  This typically happens in scenarios such as:
  
  When creating or maintaining generic material hierarchies or generic material relationships.
  When performing product allocation or planning where generic materials and their variants are involved.
  When the system tries to validate or replicate variant data between related generic materials.
  
  
  Common Causes:
  
  Incomplete Variant Assignment: Not all variants of the generic material &1 have been assigned or created for generic material &2.
  Data Inconsistency: Variants exist for one generic material but are missing or not maintained for the related generic material.
  Incorrect Configuration: The variant configuration or material master data setup is incomplete or inconsistent.
  Master Data Synchronization Issues: In integrated systems (e.g., ERP and APO), master data replication or synchronization might be incomplete.
  
  
  Solution / How to Fix:
  
  
  Check Variant Assignments:
  
  Verify that all variants of the generic material &1 exist and are correctly assigned to generic material &2.
  Use transaction codes like MM03 (Display Material) or CU50 (Change Variant Configuration) to check variant assignments.
  
  
  
  Maintain Missing Variants:
  
  Create or assign the missing variants for the generic material &2.
  Ensure that the variant characteristics and values are consistent.
  
  
  
  Review Material Master Data:
  
  Check the material master records for both generic materials.
  Ensure that the variant configuration views and classification data are complete.
  
  
  
  Check Configuration Settings:
  
  Review the variant configuration settings in SPRO under Logistics ? Production ? Variant Configuration.
  Ensure that the generic material relationships and variant dependencies are correctly defined.
  
  
  
  Synchronize Master Data:
  
  If using APO or other integrated systems, ensure that master data replication is complete and consistent.
  Use tools like CIF (Core Interface) to replicate master data properly.
  
  
  
  Consult SAP Notes / Support:
  
  Search for SAP Notes related to WRF_APC055 for any known issues or patches.
  If the problem persists, consider raising a support ticket with SAP.
  
  
  
  
  Additional Information:
  
  This error is often encountered during planning runs, product allocation, or variant configuration processes.
  It highlights the importance of consistent master data maintenance for generic materials and their variants.
  Proper training and process controls can help avoid such inconsistencies.
