How To Fix KD302 - Cost center &, cost element &: Splitting is not possible

KD302 - Overview

• Message type: E = Error

• Message class: KD - CO Settlement

• Message number: 302

• Message text: Cost center &, cost element &: Splitting is not possible

What causes this issue?

Cost element &V2& cannot be split for cost center &V1&, period(s) &V3&,
because:
the total of the activity type equivalence numbers is zero. Therefore,
there is no splitting base for this cost element.
the target costs for cost object hierarchies are zero. This means
there is no distribution basis for this cost element.

System Response

The values for cost element &V2& are not split. They cannot be taken
into account for further processing.

How to fix this error?

For cost centers:
Maintain the equivalence numbers for the activity types in cost center
&V1& so that total is not zero.
For cost object hierarchies:
Check the cost element group in target version 0. There must be target
costs in this cost element group, which the distribution can use to
split the actual costs.

KD302 - Details

• The SAP error message KD302 ("Cost center &, cost element &: Splitting is not possible") typically occurs in the context of controlling (CO) when trying to post costs to a cost center and cost element combination that cannot be split. This error can arise due to several reasons, and understanding the cause is essential for finding a solution.
  Causes of KD302 Error
  
  
  Cost Element Configuration: The cost element may not be configured to allow splitting. In SAP, certain cost elements are set up as "primary" or "secondary," and only specific types can be split.
  
  
  Cost Center Configuration: The cost center may not be set up to allow for splitting of costs. This can happen if the cost center is not active or if it has restrictions on how costs can be allocated.
  
  
  Transaction Type: The type of transaction being processed may not support splitting. For example, certain types of postings or allocations may not
