• What is the cause and solution for SAP error message /SAPAPO/OM_ERROR164 - Read routine has no input data ?

  The SAP error message /SAPAPO/OM_ERROR164 indicates that a read routine in the Advanced Planning and Optimization (APO) module does not have any input data to process. This error typically occurs during the execution of a planning function or when trying to read data from a data source, and it can be caused by several factors.
  Causes:
  
  
  Missing Input Data: The most common cause is that the input data required for the read routine is not available. This could be due to:
  
  No data being selected for the planning run.
  Filters applied that exclude all relevant data.
  Data not being loaded into the system.
  
  
  
  Incorrect Configuration: The configuration of the planning function or the data source may be incorrect, leading to the read routine not being able to find the necessary input data.
  
  
  Data Source Issues: The data source from which the read routine is supposed to pull data may not be set up correctly or may not contain any data.
  
  
  Authorization Issues: Sometimes, authorization issues can prevent the read routine from accessing the necessary data.
  
  
  Solutions:
  
  
  Check Input Data: Verify that the input data for the planning function is available. You can do this by:
  
  Running a data selection to see if any data is returned.
  Checking the filters applied to ensure they are not too restrictive.
  
  
  
  Review Configuration: Ensure that the planning function and the associated read routine are configured correctly. This includes:
  
  Checking the settings in the planning function to ensure they are pointing to the correct data sources.
  Reviewing the read routine to ensure it is set up to read from the correct InfoProvider or data source.
  
  
  
  Load Data: If the required data is not present, ensure that the data is loaded into the system. This may involve running data extraction processes or loading data from external sources.
  
  
  Check Authorizations: Ensure that the user executing the planning function has the necessary authorizations to access the data.
  
  
  Debugging: If the issue persists, consider debugging the planning function to identify where the read routine is failing. This may require technical expertise in SAP APO.
  
  
  Related Information:
  
  Transaction Codes: You may want to use transaction codes like /SAPAPO/OM to access the planning functions and check their configurations.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
