• What is the cause and solution for SAP error message W_CB360 - An unit must be specified ?

  SAP Error Message:
  
  W_CB360 - An unit must be specified
  
  Cause:
  This warning message occurs when a unit of measure (UoM) is missing or not specified in a transaction or master data record where it is mandatory. For example, when entering quantities in goods movements, production orders, or material master data, the system requires a unit of measure to process the data correctly. If the unit is not entered or is left blank, SAP triggers this warning.
  
  When does it typically occur?
  
  During goods receipt or goods issue postings.
  When creating or changing production orders or process orders.
  While maintaining material master data (e.g., base unit of measure or alternative units).
  In sales or purchase order processing when quantity is entered without a unit.
  In batch management or inventory transactions where unit specification is mandatory.
  
  
  Solution:
  
  
  Specify the Unit of Measure:
  
  Always enter the appropriate unit of measure for the quantity fields. For example, "PC" (pieces), "KG" (kilograms), "L" (liters), etc.
  
  
  Check Material Master Data:
  
  Ensure that the material master has a valid base unit of measure maintained in transaction MM02 (Change Material). The base unit of measure must be defined and consistent.
  
  
  Verify Transaction Data Entry:
  
  When entering quantities in transactions (e.g., MIGO, MB1A, CO01), make sure the unit field is filled correctly.
  
  
  User Exits or Custom Code:
  
  If the error arises due to custom developments or user exits, check the code to ensure that the unit of measure is passed correctly to the SAP standard functions.
  
  
  Configuration Check:
  
  In some cases, the unit of measure might not be assigned or configured properly in the system. Check the unit of measure settings in SPRO under Logistics ? General ? Units of Measure.
  
  
  
  Additional Information:
  
  Message Class: CB3 (related to production orders and capacity planning)
  Message Type: Warning (W) — the system allows you to continue but recommends correction.
  Transaction Codes: MIGO, MB1A, CO01, MM02, etc.
  Related Tables: MARA (Material Master), T006 (Units of Measure)
  
  
  Summary:
  The warning W_CB360 - An unit must be specified indicates that a unit of measure is missing where it is required. To resolve it, always enter a valid unit of measure in the relevant fields and ensure the material master and configuration settings are correct.
