  The SAP error message /SAPAPO/MAT135 Lot size profile &3 not deleted (Reference to product &1, location &2) typically occurs in the SAP Advanced Planning and Optimization (APO) module when there is an attempt to delete a lot size profile that is still being referenced by a product at a specific location. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Active References: The lot size profile you are trying to delete is still assigned to one or more products at the specified location. This means that the system cannot delete the profile because it is still in use.
  Data Integrity: SAP enforces data integrity rules to ensure that no orphaned or invalid references are left in the system, which is why the deletion is blocked.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check References:
  
  Use transaction code /SAPAPO/MAT1 (or the relevant transaction for your version) to check which products are using the lot size profile.
  Navigate to the product master data for the product &1 at location &2 and check the lot size profile assignment.
  
  
  
  Remove the Lot Size Profile:
  
  If the lot size profile is assigned to the product, you will need to remove it from the product master data.
  Go to the product master data and change the lot size profile to another valid profile or set it to blank if appropriate.
  
  
  
  Delete the Lot Size Profile:
  
  Once the lot size profile is no longer referenced by any products, you can attempt to delete it again using the appropriate transaction (e.g., /SAPAPO/MAT1 or /SAPAPO/MAT2).
  
  
  
  Check for Other Dependencies:
  
  Ensure that there are no other dependencies or references to the lot size profile in other areas of the system, such as planning books or other master data.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as /SAPAPO/MAT1 for product master data maintenance and /SAPAPO/MAT2 for changing product data.
