  The SAP error message BM034 ("No measurement unit is assigned to ISO code &") typically occurs when there is an attempt to use a measurement unit that is not properly defined or linked to an ISO code in the SAP system. This can happen in various contexts, such as when creating or processing materials, purchase orders, or other documents that require measurement units.
  Cause:
