• What is the cause and solution for SAP error message /UI2/ABAP_PB004 - Basis Chips: Reset Cache ?

  The SAP error message /UI2/ABAP_PB004 typically relates to issues with the cache in the SAP Fiori/UI2 framework. This error can occur when there are inconsistencies or outdated data in the cache, which can affect the performance and functionality of the Fiori applications.
  Cause:
  
  Cache Inconsistency: The cache may contain outdated or corrupted data, leading to issues when trying to access Fiori applications.
  Changes in Backend: If there have been recent changes in the backend (like updates to OData services, changes in the data model, etc.), the cache may not reflect these changes.
  Transport Issues: If there are transport requests that have not been properly imported or activated, it can lead to cache inconsistencies.
  
  Solution:
  To resolve the /UI2/ABAP_PB004 error, you can follow these steps:
  
  
  Reset the Cache:
  
  Go to the SAP GUI and execute transaction code /UI2/FLP.
  In the Fiori Launchpad, you can reset the cache by navigating to the "User Preferences" and selecting the option to clear the cache.
  Alternatively, you can use the transaction /UI2/INVALIDATE_CACHE to invalidate the cache for the entire system.
  
  
  
  Clear Browser Cache:
  
  Sometimes, the issue may also be related to the browser cache. Clear the browser cache and cookies, and then try accessing the Fiori applications again.
