OBYC-EIN EKG G/L accounts shows message KI280 during MIRO

[renming_yin]

Hi Expert

We get one error message KI280 for G/L accounts determined by OBYC EIN and EKG in MIRO.

The context is we are in S/4 and margin Analysis is activated, and the purchase account EIN/EKG is used and their G/L accounts are not cost elements.

For this specific case, we have sales order related Purchase order - PO account assignment Category M, there is no issue during MIGO for these purchase accounts EIN/EKG.

PO price is changed after MIGO, and during MIRO, the difference due to PO price change triggers the posting to EIN/EKG, and system fills the Profitability segments PSG number to these two EIN/EKG lines, then the error message KI280 pops up when we attempts to post.

Hi

The error KI280 in MIRO is caused because the system tries to post to a G/L account (EIN/EKG) with a profitability segment (PSG) in a scenario where the account is not defined as a cost element. In S/4HANA with Margin Analysis activated, whenever a profitability segment is involved in the accounting line, the system expects the G/L account to be a cost element, especially for postings with PSG attributes.

In your case, during MIGO everything works fine because no profitability segment is triggered at that point. However, during MIRO, due to the price change after goods receipt, the system determines that the difference should be posted to the EIN/EKG account and at the same time it fills a PSG number because of the sales order linkage and Margin Analysis.

Since the EIN/EKG G/L accounts are not created as cost elements in transaction KA01 or via app "Manage Cost Elements", and because PSG is filled, the system throws error KI280 indicating that it cannot post to this account with a PSG.

To resolve this:

1. Either convert the affected G/L accounts used for EIN and EKG into cost elements (typically of category 1 - Primary cost element), which allows PSG postings.
2. Or avoid the profitability segment assignment for these lines, which might require adjusting account determination or the configuration of the relevant posting logic in the system to bypass PSG derivation for these accounts.

Option 1 is recommended if PSG-based analysis is expected and you want to allow the system to post price differences with profitability segments. Ensure the account is not restricted from PSG in its field status or derivation rules.
