• What is the cause and solution for SAP error message R7388 - Dimension &1 already used in InfoCube &2 ?

  The SAP error message R7388 indicates that a dimension (in this case, represented by &1) is already being used in an InfoCube (represented by &2). This typically occurs when you are trying to add a dimension to an InfoCube that already contains that dimension, which is not allowed in SAP BW (Business Warehouse).
  Cause:
  
  Duplicate Dimension: The dimension you are trying to add is already part of the InfoCube.
  Modeling Error: There may be a misunderstanding in the modeling process where the same dimension is being attempted to be added again.
  Incorrect InfoObject Assignment: The InfoObject you are trying to assign may have been previously assigned to the InfoCube.
  
  Solution:
  
  
  Check Existing Dimensions: Review the existing dimensions of the InfoCube to confirm that the dimension you are trying to add is indeed already included.
  
  Go to the InfoCube in the Data Warehousing Workbench and check the dimensions tab.
  
  
  
  Remove Duplicate Attempt: If you find that the dimension is already present, you do not need to add it again. Simply proceed with your modeling without attempting to add the duplicate dimension.
  
  
  Modify Existing Dimension: If you need to change the properties of the existing dimension, you can do so without trying to add it again.
  
  
  Revisit Modeling Requirements: If you believe you need a different dimension, ensure that you are using the correct InfoObject and that it is not already part of the InfoCube.
  
  
  Consult Documentation: If you are unsure about the structure of your InfoCube or dimensions, refer to SAP documentation or consult with a BW expert to clarify the relationships and requirements.
  
  
  Related Information:
  
  InfoCube Structure: Understanding the structure of InfoCubes and how dimensions relate to fact tables is crucial in BW modeling.
