• What is the cause and solution for SAP error message W0015 - ID must be set to 1 (value-only material) for one material type ?

  SAP Error Message:
  
  W0015: ID must be set to 1 (value-only material)
  
  Cause:
  This warning message occurs when you are trying to create or change a material of a specific material type that is configured as a value-only material in SAP, but the ID field (usually the valuation type or a related identifier) is not set to the required value of 1.
  
  Value-only materials are materials that do not have stock quantities managed in the system but only have a value (e.g., services, consumables without stock).
  For such materials, SAP requires the ID (often the valuation type or a similar key field) to be set to 1 to indicate that there is only one valuation or no stock management.
  
  
  When does this happen?
  
  When creating or changing materials of a material type configured as value-only.
  When the system expects the ID field to be fixed to 1 but finds a different value or no value.
  This is often related to material master valuation views or accounting views where valuation types or IDs are relevant.
  
  
  Solution:
  
  
  Set the ID to 1:
  
  When maintaining the material master, ensure that the ID field (valuation type or the relevant field) is set to 1.
  This is usually done in the Accounting 1 or Valuation view of the material master.
  
  
  
  Check material type configuration:
  
  Verify if the material type is configured as a value-only material.
  Use transaction OMS2 to check material type settings.
  If the material type is not supposed to be value-only, adjust the configuration accordingly.
  
  
  
  Adjust valuation type settings:
  
  If multiple valuation types are not allowed for this material type, ensure only valuation type 1 is used.
  This can be controlled in the valuation area or accounting settings.
  
  
  
  Consult customizing:
  
  Check if the material type is set to allow multiple valuation types or if it is restricted to a single valuation type (ID=1).
  Adjust if necessary in IMG under Logistics - General > Material Master > Settings for Key Fields > Define Material Types.
  
  
  
  
  Related Information:
  
  Material Type: Defines the general behavior of the material (stockable, non-stockable, value-only, etc.).
  Valuation Type: Used to differentiate stock valuation for the same material (e.g., different batches, plants).
  Value-only Material: Material that does not have stock quantity but only value (e.g., services).
  Transaction Codes:
  
  MM01/MM02: Create/Change Material Master
  OMS2: Material Type Configuration
  OMWN: Valuation Type Configuration
  
  
  
  
  Summary:
  
  Cause: Material type is value-only, but ID (valuation type) is not set to 1.
  Solution: Set ID to 1 in material master; verify material type and valuation settings.
  Check: Material type configuration in OMS2 and valuation type settings.
