  The SAP error message /SAPAPO/SNP523 No material was selected before calling the optimizer typically occurs in the SAP Advanced Planning and Optimization (APO) module, specifically when using the Supply Network Planning (SNP) optimizer. This error indicates that the optimizer was invoked without any materials being selected for processing, which is a prerequisite for the optimization process.

  Review Planning Object Structure: Verify that the planning object structure includes the necessary materials and that it is correctly configured.
  Data Validation: Check the master data (material master, location master, etc.) and transaction data (forecast, stock levels, etc.) to ensure that they are correctly set up and that there are no inconsistencies.
  Run a Test: After making the necessary adjustments, run a test planning run to see if the error persists.
