How To Fix ESH_OM_OBJ_MODEL_RP2851 - Attribute &1 has no dimension but scale &2 is of dimension &4 (uom &3)

SAP Error Message - Details

• Message type: E = Error

• Message class: ESH_OM_OBJ_MODEL_RP2 - Object Model Repository (2)

• Message number: 851

• Message text: Attribute &1 has no dimension but scale &2 is of dimension &4 (uom &3)

What causes this issue?

A ranking factor attribute can have a dimension and a scale can have a
unit of measure (uom) which itself has a dimension.
Here the attribute is assigned to scale &v2& but the following condition
is not fulfilled:
As scale &v2& has a unit of measure with a dimension the attribute must
be of the same dimension.

• What is the cause and solution for SAP error message ESH_OM_OBJ_MODEL_RP2851 - Attribute &1 has no dimension but scale &2 is of dimension &4 (uom &3) ?

  The SAP error message ESH_OM_OBJ_MODEL_RP2851 indicates an issue related to the handling of attributes in the context of object models, particularly when dealing with units of measure (UOM) and their dimensions. Here’s a breakdown of the components of the error message and potential solutions:
  Cause:
  
  Attribute Definition: The attribute specified (denoted as &1) is defined without a dimension, meaning it does not have a specific measurement context (like length, weight, etc.).
  Scale Definition: The scale (denoted as &2) is associated with a unit of measure (UOM) that has a dimension (denoted as &4) and is specified as &3. This creates a conflict because the attribute does not have a dimension, but the scale does.
  Data Inconsistency: This error often arises from inconsistencies in the data model where attributes and their associated scales and units of measure are not aligned correctly.
  
  Solution:
  
  Check Attribute Configuration: Review the configuration of the attribute (identified by &1) in the relevant object model. Ensure that it is defined correctly and has the appropriate dimension if it is supposed to be associated with a scale that has a dimension.
  Adjust Scale or UOM: If the attribute is intended to be dimensionless, ensure that the scale (and its associated UOM) is also defined as dimensionless. Alternatively, if the scale is meant to have a dimension, consider modifying the attribute to include the appropriate dimension.
  Data Model Review: Conduct a thorough review of the data model to ensure that all attributes, scales, and UOMs are correctly defined and aligned. This may involve checking the underlying database tables or configuration settings in the SAP system.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on defining attributes, scales, and units of measure correctly within the context of your specific application or module.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling attributes and dimensions.
  Community Forums: Engage with SAP community forums or support channels where similar issues may have been discussed, and solutions shared.
  Testing: After making changes, conduct thorough testing to ensure that the error is resolved and that the data model behaves as expected.
  
  By addressing the configuration of the attribute and ensuring consistency with the associated scale and UOM, you should be able to resolve the error ESH_OM_OBJ_MODEL_RP2851.
