  Error Message
  VMP_MSG305: Multiple alternatives selected for material &1
  
  Cause
  This error occurs in SAP Variant Configuration (LO-VC) when the system detects that more than one alternative (variant) has been selected for a material that should have a unique configuration or selection. In other words, the system expects a single valid alternative for the material, but multiple alternatives have been chosen simultaneously, which leads to a conflict.
  This typically happens during:
  
  Sales order processing with configurable materials.
  When the configuration profile or dependencies allow multiple conflicting selections.
  When the selection conditions or constraints are not properly maintained, allowing multiple alternatives to be selected.
  
  
  Explanation
  In SAP Variant Configuration, a material can have multiple alternatives (variants) defined, but only one alternative should be selected at a time for a given configuration. If the system finds multiple alternatives selected, it cannot determine which one to use, hence the error.
  
  Solution
  
  
  Check Configuration Profile and Dependencies:
  
  Review the configuration profile assigned to the material.
  Verify the dependencies (preconditions, selection conditions, constraints) to ensure they prevent multiple alternatives from being selected simultaneously.
  Adjust or create constraints to enforce mutually exclusive selection of alternatives.
  
  
  
  Review Characteristics and Class Assignments:
  
  Check the characteristics assigned to the material and their allowed values.
  Ensure that the characteristics and their values are set up so that only one alternative can be selected.
  
  
  
  Check Sales Order or Configuration Input:
  
  In the sales order or configuration screen, verify that the user has not selected multiple alternatives.
  Correct the selection to only one valid alternative.
  
  
  
  Use Configuration Simulation:
  
  Use transaction CU50 or CU53 to simulate the configuration and identify where multiple alternatives are being selected.
  Adjust the configuration accordingly.
  
  
  
  Check Variant Table Entries:
  
  If alternatives are maintained in variant tables, ensure that the entries do not overlap or conflict.
  
  
  
  Consult SAP Notes:
  
  Check for any SAP Notes related to VMP_MSG305 for specific patches or known issues.
