• What is the cause and solution for SAP error message WRF_APC035 - No units of measure exist for material &1 ?

  SAP Error Message:
  
  WRF_APC035 No units of measure exist for material &1
  
  Cause:
  This error occurs when the system tries to process a material in a transaction or function (often related to Advanced Planning and Optimization - APO or other SCM components) but cannot find any units of measure (UoM) defined for that material in the system. Essentially, the material master record lacks the necessary unit of measure data, which is mandatory for quantity-related operations.
  
  Explanation:
  
  Every material in SAP must have at least one unit of measure defined (usually the base unit of measure).
  The error indicates that the material master data is incomplete or incorrectly maintained.
  This can happen if the material was created without specifying a base unit of measure or if the unit of measure data was deleted or corrupted.
  It can also occur if the system is trying to access a material that does not exist or is not properly replicated in the APO system.
  
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to transaction MM03 (Display Material).
  Enter the material number &1 (the material referenced in the error).
  Check the Basic Data 1 view to verify if a Base Unit of Measure is maintained.
  Also check other relevant views if necessary.
  
  
  
  Maintain Unit of Measure:
  
  If the base unit of measure is missing, use MM02 (Change Material) to maintain it.
  Ensure that the base unit of measure is correctly defined and consistent with business requirements.
  
  
  
  Check Material Existence and Replication:
  
  If working with APO or SCM, verify that the material is properly replicated from ECC to APO.
  Use transaction /SAPAPO/MAT1 or related APO transactions to check material master data.
  If missing, perform the necessary replication steps.
  
  
  
  Check Customizing and Integration Settings:
  
  Verify that the integration between ECC and APO is correctly configured.
  Check if any filters or settings are preventing the material data from being transferred.
  
  
  
  Re-run the Process:
  
  After correcting the material master data, re-run the process or transaction that caused the error.
  
  
  
  
  Additional Information:
  
  Unit of Measure (UoM) is a critical attribute for materials as it defines how quantities are measured and processed.
  In APO, the base unit of measure must be consistent with ECC to avoid synchronization issues.
  If the error occurs during planning or forecasting, it may halt the process until the material master data is corrected.
  Always ensure that material master data is complete and consistent across all systems involved.

  Error
  WRF_APC035 No units of measure exist for material &1
  
  
  Cause
  Material master lacks unit of measure data
  
  
  Solution
  Maintain base unit of measure in material master (MM02) and ensure proper replication to APO
