• What is the cause and solution for SAP error message UMK638 - Link between customer measure '&2' and provider measure '&1' deleted ?

  The SAP error message UMK638 indicates that there is a problem with the link between a customer measure and a provider measure in the context of SAP BW (Business Warehouse) or SAP Analytics. This error typically arises when the relationship or mapping between these two measures has been deleted or is no longer valid.
  Cause:
  
  Deleted Link: The most common cause is that the link between the customer measure (which is a measure defined by the user) and the provider measure (which is a standard measure provided by SAP) has been deleted or is missing.
  Configuration Changes: Changes in the configuration of the InfoProvider or the underlying data model can lead to this error. For example, if the InfoObject or InfoProvider was modified or deleted.
  Transport Issues: If changes were transported from one system to another (e.g., from development to production), and the transport did not include all necessary objects, this could lead to broken links.
  Data Model Changes: Changes in the data model, such as changes in the underlying database or data source, can also lead to this error.
  
  Solution:
  
  Recreate the Link: If the link has been deleted, you will need to recreate it. This can typically be done in the SAP BW modeling tools by navigating to the relevant InfoProvider and re-establishing the link between the customer measure and the provider measure.
  Check Configuration: Review the configuration of the InfoProvider and ensure that all necessary measures are correctly defined and linked.
  Transport Check: If the issue arose after a transport, check the transport logs to ensure that all necessary objects were included in the transport. If not, you may need to re-transport the missing objects.
  Data Model Review: Review any recent changes made to the data model to ensure that they did not inadvertently affect the measures in question.
