• What is the cause and solution for SAP error message AC590 - You must enter an alternative rule ?

  The SAP error message AC590 ("You must enter an alternative rule") typically occurs in the context of Asset Accounting (FI-AA) when you are trying to post an asset transaction, and the system requires an alternative rule to be specified but it has not been provided.
  Cause:
  The error is usually caused by one of the following reasons:
  
  Missing Alternative Rule: The transaction you are trying to execute requires an alternative depreciation calculation rule, but none has been specified in the asset master data or during the transaction entry.
  Configuration Issues: The configuration settings for asset accounting may not be set up correctly, leading to the requirement for an alternative rule that is not defined.
  Transaction Type: Certain transaction types may require an alternative rule to be specified, and if it is not, the system will throw this error.
  
  Solution:
  To resolve the AC590 error, you can take the following steps:
  
  
  Check Asset Master Data:
  
  Go to the asset master record (transaction code AS02) and check if an alternative rule is defined. If not, you may need to enter one.
  Ensure that the asset class assigned to the asset allows for alternative rules.
  
  
  
  Define Alternative Rules:
  
  If you need to create or modify an alternative rule, you can do this in the configuration settings. Use transaction code OAYZ to define alternative rules for depreciation.
  Make sure that the alternative rule is correctly configured and linked to the appropriate asset classes.
  
  
  
  Review Transaction Entry:
  
  When entering a transaction, ensure that you are specifying the alternative rule if it is required. This may involve checking the transaction type and ensuring that all necessary fields are filled out.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to Asset Accounting for more detailed information on how to set up and use alternative rules.

  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as AS01 (Create Asset), AS02 (Change Asset), and OAYZ (Define Alternative Rules).
  Asset Classes: Understand how asset classes are configured and how they relate to alternative rules.
  Depreciation Methods: Review the different depreciation methods and how they interact with alternative rules in your asset accounting setup.
