  • What is the cause and solution for SAP error message WP208 - ISO unit of measurement & not maintained for material & ?

    Certainly! Here's detailed information about the SAP error message WP208:


    SAP Error Message: WP208

    Text: ISO unit of measurement & not maintained for material &


    Cause:

    This error occurs when the system tries to process a material that requires an ISO unit of measurement (UoM) to be maintained, but the ISO UoM is missing or not maintained in the material master record.

    • The ISO unit of measurement is a standardized unit code defined by the International Organization for Standardization (ISO).
    • Certain SAP processes, especially those involving integration with external systems, reporting, or compliance with international standards, require the ISO UoM to be maintained.
    • If the ISO UoM field is empty or incorrectly maintained in the material master (usually in the Basic Data 1 view or related UoM fields), the system throws this error.

    Where is the ISO Unit of Measurement maintained?

    • Transaction MM02 (Change Material Master)
    • Navigate to Basic Data 1 tab
    • Look for the field ISO Unit of Measure (field name: MEISO)
    • This field should contain the ISO code corresponding to the base unit of measure of the material.

    Solution:

    1. Check the material master:

      • Use transaction MM03 to display the material.
      • Go to Basic Data 1 tab.
      • Verify if the ISO Unit of Measure field is filled.
    2. Maintain the ISO unit of measurement:

      • If empty or incorrect, use MM02 to update the material master.
      • Enter the correct ISO unit of measurement code that corresponds to the base unit of measure.
      • For example, if the base unit is "KG" (kilogram), the ISO code should be "KGM".
    3. Save the changes.

    4. Re-run the process that caused the error to confirm it is resolved.


    Additional Information:

    • ISO Unit of Measure Codes:
      These are standardized codes like "KGM" for kilogram, "LTR" for liter, "MTR" for meter, etc.
      You can find the list of ISO UoM codes in SAP table T006A or via SAP help/documentation.

    • Why is this important?
      Maintaining the ISO unit ensures consistency in data exchange, reporting, and compliance with international standards.

    • Related Tables:

      • MARA (General Material Data) — field MEISO stores the ISO unit of measure.
      • T006A — ISO unit of measure codes.
    • Related Notes / SAP OSS Messages:
      Sometimes SAP releases notes or patches related to unit of measure handling. Check SAP Support Portal if the problem persists after maintaining the ISO UoM.


    Summary:

    Aspect Details
    Error Message WP208: ISO unit of measurement & not maintained for material &
