• What is the cause and solution for SAP error message ME126 - Please enter material with same inv. management in both plants ?

  The SAP error message ME126 ("Please enter material with same inv. management in both plants") typically occurs when you are trying to create or change a purchasing document (like a purchase order) that involves materials from different plants, but the inventory management settings for those materials are not consistent across the plants.
  Cause:
  The error is triggered when:
  
  You are attempting to create a purchasing document that includes materials from multiple plants.
  The materials in question have different inventory management settings (e.g., one plant may have the material set up for inventory management while the other does not).
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Material Master Data:
  
  Go to the Material Master (Transaction Code: MM03) and check the inventory management settings for the materials in both plants.
  Ensure that the materials have the same inventory management settings (e.g., whether they are managed in stock or not).
  
  
  
  Adjust Inventory Management Settings:
  
  If the settings are different, you may need to adjust the inventory management settings for one of the plants to match the other. This can be done in the Material Master (Transaction Code: MM02) by editing the relevant views.
  
  
  
  Use the Same Plant:
  
  If the materials must remain with different inventory management settings, consider creating separate purchasing documents for each plant instead of combining them into one.
  
  
  
  Consult with Your SAP Team:
  
  If you are unsure about making changes to the material master or if the issue persists, consult with your SAP functional team or a colleague who has expertise in material management.
