  The SAP error message W#528 "Quantity in main item calculated new" typically occurs in the context of sales order processing, delivery, or billing when there is a discrepancy between the quantities of the main item and its sub-items (or components).

  Data Inconsistencies: Inconsistent data in the sales order or delivery documents can trigger this error.
  
  Solution:
  
  Check Item Quantities: Review the quantities of the main item and its sub-items. Ensure that they are consistent and that the total quantity of the sub-items matches the main item.
  Adjust Quantities: If there are discrepancies, adjust the quantities of the sub-items or the main item as necessary to ensure they align.
  Review Item Configuration: Check the configuration of the item categories in the sales order. Ensure that they are set up correctly to handle item splitting.
  Recreate the Document: In some cases, it may be easier to recreate the sales order or delivery document to resolve any underlying issues.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance related to your version of SAP and the context in which the error occurs.
