  The SAP error message ML4HDOC001 indicates that there is an ambiguous quantity unit for a material with a specific cost estimate number. This typically occurs in the context of material management and cost accounting when the system cannot determine which unit of measure to use for a particular material.

  Missing or Incorrect Data: The cost estimate may not have the necessary data or may be incorrectly set up, leading to ambiguity in the unit of measure.
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM03) and check the units of measure defined for the material. Ensure that the base unit of measure is correctly set and that there are no conflicting entries.

  Adjust Configuration:
  
  If necessary, adjust the configuration in the material master or the cost estimate to resolve any ambiguities. This may involve setting a default unit of measure or ensuring that the relevant units are properly linked to the cost estimate.
