  Certainly! Here's a detailed explanation regarding the SAP error message WG100: "Order quantity increased by quantity of an identical item":
  
  SAP Error Message: WG100
  Message Text:
  
  Order quantity increased by quantity of an identical item
  
  Cause
  This message typically occurs in SAP Sales and Distribution (SD) or Production Planning (PP) modules when you try to create or change a sales order or production order and enter multiple line items with the same material and identical item characteristics (e.g., same item category, schedule line, or configuration). Instead of creating separate line items for the same material, SAP automatically combines or consolidates these quantities into a single line item.
  The system detects that the new item you are trying to add is identical to an existing item in the order and therefore increases the quantity of the existing item rather than creating a new line.
  
  When does it occur?
  
  When entering multiple order items with the same material number and identical item details.
  When copying or referencing orders where identical items exist.
  When using configuration or variant management and the system identifies identical variants.
  When the system is set to avoid duplicate line items for the same material.
  
  
  Solution
  
  
  Check if combining quantities is acceptable:
  
  Usually, this message is informational and not an error that stops processing. SAP is informing you that it has increased the quantity of an existing item rather than creating a duplicate line.
  
  
  If you want separate line items for the same material:  
  
  Change the item characteristics so that SAP treats them as different items. For example, use different item categories, schedule lines, or add item-specific data that differentiates them.
  Use different configuration or variant settings if applicable.
  Use different sales order item numbers or references.
  
  
  
  Review your business process:  
  
  Determine if combining quantities is appropriate for your order processing.
  If separate lines are required for pricing, delivery, or billing reasons, adjust the order entry accordingly.
  
  
  
  System settings:  
  
  Check if any user exits, BAdIs, or custom logic is influencing item consolidation.
  Review the sales order type and item category settings that might control item duplication behavior.
