How To Fix R7675 - The line item dimension &1 is already assigned to characteristic &2

SAP Error Message - Details

• Message type: E = Error

• Message class: R7 - BW: Data basis

• Message number: 675

• Message text: The line item dimension &1 is already assigned to characteristic &2

What causes this issue?

The selected dimension was defined as a "Line Item Dimension", meaning
a dimension that should contain exactly one characteristic (for
example, document number).
This is a special case for the dimension definition whereby a pointer
is not written to a dimension table in the fact table of the InfoCube
(as usual), but rather directly to the (SID) value of the
characteristic.
Several characteristics should now be assigned to the selected
dimension. This is not possible; a line item dimension can only include
exactly one characteristic.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Decide which characteristic should be assigned to the "line item
dimension" and assign all other characteristics to other dimensions or
define the dimension as a normal dimension.

• What is the cause and solution for SAP error message R7675 - The line item dimension &1 is already assigned to characteristic &2 ?

  The SAP error message R7675 indicates that there is an issue with the assignment of a line item dimension to a characteristic in your SAP system. This typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when you are trying to assign a dimension to a characteristic that has already been assigned.
  Cause:
  The error arises when:
  
  You attempt to assign a line item dimension (like a key figure) to a characteristic that is already linked to another line item dimension.
  There is a conflict in the data model where the same characteristic is being used in multiple contexts or dimensions, leading to ambiguity.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Assignments:
  
  Go to the relevant data model or InfoObject in the SAP BW or HANA system.
  Check the existing assignments of the characteristic in question to see if it is already linked to another line item dimension.
  
  
  
  Remove or Modify Assignments:
  
  If the characteristic is already assigned to a different line item dimension, you may need to remove that assignment before you can assign it to the new dimension.
  Alternatively, consider whether you can modify your data model to avoid the conflict.
  
  
  
  Review Data Model Design:
  
  Ensure that your data model design adheres to best practices. Each characteristic should ideally be assigned to only one line item dimension to avoid conflicts.
  If necessary, redesign the data model to separate the dimensions and characteristics appropriately.
  
  
  
  Check for Transport Issues:
  
  If this error occurred after a transport, ensure that all objects were transported correctly and that there are no inconsistencies in the target system.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to your specific version of SAP BW or HANA for any additional guidance or known issues.
  
  
  
  Seek Help from SAP Support:
  
  If the issue persists and you cannot find a resolution, consider reaching out to SAP support for assistance. Provide them with the error message and context for better troubleshooting.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context.
  Data Modeling Best Practices: Familiarize yourself with best practices for data modeling in SAP BW or HANA to prevent similar issues in the future.
  Training and Documentation: Consider training resources or documentation on SAP BW or HANA data modeling to enhance your understanding of dimensions and characteristics.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
