Smart SAP Assistant

• What is the cause and solution for SAP error message WA321 - No subobject type selected ?

  The SAP error message WA321 No subobject type selected typically occurs in the context of Asset Accounting (FI-AA) or other modules where you need to specify a subobject type but have not done so.
  
  Cause:
  
  The error WA321 No subobject type selected arises because the system expects a subobject type to be entered or selected, but this field is left blank.
  This usually happens when you are trying to post or process an asset transaction, and the asset master or transaction requires a subobject type (a more detailed classification of the asset or cost object).
  The subobject type is often linked to cost objects, internal orders, or other controlling objects that require further breakdown.
  
  
  Solution:
  
  
  Enter the Subobject Type:
  
  When the system prompts for a subobject type, enter the appropriate value.
  The subobject type is usually defined in your controlling or asset accounting configuration.
  If you are unsure which subobject type to enter, consult your controlling or asset accounting team.
  
  
  
  Check Asset Master Data:
  
  Verify if the asset master record requires a subobject type.
  If yes, ensure that the subobject type is maintained correctly in the asset master or during the transaction.
  
  
  
  Configuration Check:
  
  In some cases, the subobject type is mandatory due to configuration in the controlling area or asset accounting settings.
  Check the configuration for the controlling area or asset class to see if subobject types are mandatory.
  Transaction codes like OKKP (Controlling Area Settings) or OAYR (Asset Accounting Settings) might be relevant.
  
  
  
  User Input:
  
  If the subobject type is missing during a transaction, the user must input it manually.
  If the system should default a subobject type, check the defaulting logic or user exit/custom code.
  
  
  
  
  Related Information:
  
  Subobject Type: In SAP Controlling (CO), a subobject type is a further breakdown of a cost object, such as a cost center or internal order. It allows more granular tracking of costs.
  Asset Accounting (FI-AA): When assets are linked to controlling objects, subobject types help in detailed cost tracking.
  Transaction Codes:
  
  AS01/AS02/AS03 – Asset Master Data maintenance
  ABZON – Asset acquisition with vendor
  OKKP – Controlling Area Settings
  
  
  SAP Notes and Documentation:

  Summary:
  
  Cause: Missing subobject type entry where it is mandatory.
  Solution: Enter the required subobject type during the transaction or maintain it in the asset master; verify configuration settings.
  Check: Asset master data, controlling area settings, and user input during transactions.
  
  If you continue to face issues, consider debugging the transaction or checking with your SAP FI/CO consultant for specific configuration or master data corrections.
