  The SAP error message /SAPAPO/MAT104 Creation not possible (Product &1 already exists in location &2) typically occurs in the SAP Advanced Planning and Optimization (APO) module when you attempt to create a new product-location combination that already exists in the system. This error indicates that the product you are trying to create is already defined for the specified location.

  Check Existing Entries: 
  
  Use transaction codes like /SAPAPO/MAT1 or /SAPAPO/MAT2 to check if the product-location combination already exists.
