• What is the cause and solution for SAP error message VMP_MSG123 - Drag and drop not possible; materials do not match ?

  The SAP error message VMP_MSG123 ("Drag and drop not possible; materials do not match") typically occurs in the context of SAP's Material Management (MM) or Sales and Distribution (SD) modules when attempting to perform a drag-and-drop operation involving materials that are not compatible or do not meet certain criteria.
  Cause:
  
  Material Type Mismatch: The materials you are trying to drag and drop may belong to different material types or categories that are not compatible with each other.
  Different Units of Measure: The materials may have different units of measure, which can prevent them from being combined or transferred.
  Status Issues: One or both of the materials may be in a status that does not allow for the operation (e.g., blocked, inactive).
  Data Inconsistencies: There may be inconsistencies in the data related to the materials, such as missing or incorrect master data.
  Transaction Context: The context in which you are trying to perform the drag-and-drop operation may not support it (e.g., trying to move materials between different document types).
  
  Solution:
  
  Check Material Types: Ensure that the materials you are trying to drag and drop are of the same type or category. If they are not, you may need to convert or create a compatible material.
  Verify Units of Measure: Check the units of measure for both materials. If they differ, you may need to convert one of the materials to match the other.
  Review Material Status: Check the status of both materials in the system. If one is blocked or inactive, you may need to change its status to allow the operation.
  Data Validation: Validate the master data for both materials to ensure there are no inconsistencies or missing information.
  Use Alternative Methods: If drag-and-drop is not working, consider using alternative methods to transfer or combine materials, such as using the appropriate transaction codes or menus.
