How To Fix KE0C020 - Cost elements overlap in assgnmt lines &2 and &3, PA trans.str. &1,COAr&4

KE0C020 - Overview

• Message type: E = Error

• Message class: KE0C - CO-PA: Customizing checks

• Message number: 020

• Message text: Cost elements overlap in assgnmt lines &2 and &3, PA trans.str. &1,COAr&4

What causes this issue?

Assignment lines &V2& and &V3& of PA transfer structure &V1& contain
overlapping cost elements in controlling area &V4&. At least one cost
element is assigned to both lines. Consequently, this cost element
cannot be assigned correctly during settlement.
To ensure that data is settled correctly to CO-PA, you need to assign
each source cost element to one line only. A cost element can only
occur more than once in combination with different variance categories
(calculation motives, recovery indicator). If only a cost element group
and no variance category is entered for an assignment line, this cost
element group applies for all variance categories (calculation motives,
recovery indicator).

System Response

If you are <ZH>maintaining the PA transfer structure</> when you
receive this message, the system runs a validity check on the
assignment lines for the current controlling area. If overlapping cost
elements are found, the system displays a warning. Press ENTER and make
the necessary corrections.
If you receive this message <ZH>when saving the PA transfer
structure</>, the system does <ZH>not</> save the structure until you
have corrected the error. Since this validity check is performed on all
the PA transfer structures you have changed, the system may find errors
that do not apply for the current controlling area. These errors may
have been correct entries at the time they were entered which are now
incorrect due to subsequent changes to a cost element group.

How to fix this error?

Remove the overlapping cost elements by entering different cost element
groups, or remove the duplicated cost elements from the affected cost
element groups. You can display the cost elements in a cost element
group by pressing the "Display" icon next to the group name. To change
this group, choose <ZH>Extras -> Cost element group -> Change</> after
positioning the cursor on the desired group. If you want to create a
new cost element group, enter a new group name and press ENTER.

• What is the cause and solution for SAP error message KE0C020 - Cost elements overlap in assgnmt lines &2 and &3, PA trans.str. &1,COAr&4 ?

  The SAP error message KE0C020 indicates that there is an overlap in cost elements in the assignment lines of a particular transaction. This typically occurs in the context of controlling (CO) and profitability analysis (PA) when you are trying to post or process data that involves cost elements that are not allowed to overlap in the specified context.
  
  Cause:
  The error is caused by the following scenarios:
  
  Duplicate Cost Elements: The same cost element is being used in multiple assignment lines for the same transaction structure, which is not allowed.
  Incorrect Configuration: The configuration of the cost elements or the assignment lines may not be set up correctly, leading to overlaps.
  Data Entry Errors: Manual data entry errors where the same cost element is mistakenly entered multiple times in the same transaction.
  
  
  Solution:
  To resolve the KE0C020 error, you can take the following steps:
  
  
  Review Assignment Lines: Check the assignment lines for the transaction structure mentioned in the
