• What is the cause and solution for SAP error message /SAPAPO/ATP191 - Enter a check mode ?

  The SAP error message /SAPAPO/ATP191 typically indicates that a check mode needs to be specified for the Availability Check in the Advanced Planning and Optimization (APO) module. This error often arises when a user attempts to perform an availability check without defining the appropriate check mode.
  Cause:
  The error occurs because the system requires a specific check mode to determine how the availability check should be executed. The check mode defines the rules and parameters for the availability check, such as whether it should consider stock levels, planned orders, or other factors.
  Solution:
  To resolve the error, you need to specify a check mode when performing the availability check. Here are the steps to do this:
  
  
  Identify the Transaction: Determine which transaction or process you are using that triggered the error.
  
  
  Specify Check Mode:
  
  If you are using a transaction that allows you to specify a check mode (like a sales order or production order), look for a field labeled "Check Mode" or similar.
  Enter a valid check mode. Common check modes include:
  
  01: Check against available stock
  02: Check against confirmed stock
  03: Check against planned orders
  
  
  The specific check modes available may depend on your system configuration.
  
  
  
  Configuration Check: If you are unsure about which check modes are available or how to configure them, you may need to consult with your SAP Basis or APO configuration team. They can provide insights into the available check modes and how they are set up in your system.
  
  
  Testing: After specifying the check mode, re-run the transaction to see if the error persists.
