• What is the cause and solution for SAP error message WW107 - Enter a base unit of measure for value-only material & ?

  The SAP error message WW107 "Enter a base unit of measure for value-only material &" typically occurs when you are trying to create or modify a material master record for a material that is classified as a "value-only" material. This type of material does not have a physical quantity associated with it, but it still requires a base unit of measure for certain processes in SAP.
  Cause:
  The error arises because:
  
  The material is defined as a value-only material, which means it is used for accounting purposes but does not have a physical quantity.
  The base unit of measure (UoM) is not specified in the material master record, which is mandatory for value-only materials.
  
  Solution:
  To resolve this error, you need to enter a base unit of measure for the value-only material. Here are the steps to do this:
  
  
  Access Material Master Record:
  
  Go to the transaction code MM02 (Change Material) or MM01 (Create Material) in SAP.
  
  
  
  Select the Material Type:
  
  Enter the material number (if changing) or select the appropriate material type for value-only materials (e.g., material type "DIEN" for services).
  
  
  
  Navigate to Basic Data View:
  
  Go to the Basic Data view or the relevant view where the base unit of measure is defined.
  
  
  
  Enter Base Unit of Measure:
  
  In the field for the base unit of measure, enter a valid unit of measure (e.g., "EA" for each, "KG" for kilograms, etc.). Even though the material is value-only, a base UoM is still required.
  
  
  
  Save Changes:
  
  After entering the base unit of measure, save the changes to the material master record.
  
  
  
  Related Information:
  
  Material Types: Understand the different material types in SAP and their characteristics. Value-only materials are typically used for services or items that do not have a physical inventory.
