    SAP Error Message: WSTI_MLT_INV_DOC006

    Text: Error on the item structure's material number


    Cause

    This error typically occurs during the processing of inbound or outbound IDocs (Intermediate Documents) in SAP, especially in scenarios involving material master data or inventory postings. The system detects an issue with the material number specified in the item structure of the IDoc.

    Common causes include:

    • Invalid or non-existent material number: The material number referenced in the IDoc does not exist in the SAP system.
    • Incorrect material number format: The material number may not conform to the expected format or length.
    • Material master data not maintained: The material master record might be incomplete or missing required views.
    • Material number mismatch: The material number in the IDoc does not match the expected material number for the business process.
    • Leading/trailing spaces or special characters: Sometimes, the material number contains unexpected spaces or characters causing validation failure.
    • Material number conversion issues: If material number conversion routines are active (e.g., external vs internal number ranges), the number might not be correctly converted.

    Solution

    To resolve the error, follow these steps:

    1. Verify the Material Number in the IDoc:

      • Check the IDoc segment containing the material number (e.g., E1MARAM, E1MARC, or relevant segment).
      • Ensure the material number is correct, complete, and properly formatted.
    2. Check Material Master Data:

      • Use transaction MM03 to verify if the material number exists.
      • Confirm that the material master is fully maintained with all necessary views for the process (e.g., Basic Data, Plant Data).
    3. Check Number Range and Conversion:

      • If material number conversion is active, verify the conversion routines in transaction SNRO or MMNR.
      • Ensure the material number in the IDoc matches the internal number range or is properly converted.
    4. Clean Up Material Number:

      • Remove any leading/trailing spaces or special characters.
      • Use debugging or IDoc display transactions (WE02, WE05) to inspect the exact value.
    5. Reprocess or Correct the IDoc:

      • After correcting the material number or master data, reprocess the IDoc.
      • Use transaction BD87 to reprocess IDocs.
    6. Check Custom Validations or User Exits:

      • Sometimes, custom code or validations in user exits/BADIs may cause this error.
      • Review any custom logic related to material number validation.

    Related Information

    • Transactions:

      • WE02 / WE05: Display and analyze IDocs.
      • BD87: Reprocess IDocs.
