• What is the cause and solution for SAP error message AA904 - Blocking not possible. Open purchase requisition exists ?

  The SAP error message AA904: Blocking not possible. Open purchase requisition exists typically occurs in the Asset Accounting (FI-AA) module when you attempt to block an asset that has an open purchase requisition associated with it. This error is a safeguard to ensure that assets that are still tied to procurement processes are not blocked, as doing so could lead to inconsistencies in financial reporting and asset management.
  Cause:
  
  Open Purchase Requisition: The primary cause of this error is that there is an open purchase requisition linked to the asset you are trying to block. This means that there are still pending procurement activities related to that asset.
  Asset Status: The asset may be in a status that does not allow blocking due to existing commitments or transactions.
  Configuration Settings: There may be specific configuration settings in your SAP system that enforce this behavior.
  
  Solution:

  Review Asset Transactions:
  
  Check if there are any other transactions or commitments related to the asset that might prevent it from being blocked.
  
  
  
  Consult with Procurement Team:
  
  If you are unsure about the status of the purchase requisition or its necessity, consult with your procurement team to understand the implications of closing or deleting it.
