CK40N costing level doesn't show materials costed without errors

[nejo5001]

Hello,

In CK40N, on tab "Costing levels" the following is displayed:

Level No objects Mesage No COst estimates Costing msgs Status Costing status
7 12 0 12 2 KA Costed Without Errors
6 40 0 40 114 KF Costed with Errors
5 286 0 286 202 KF Costed with Errors
4 489 0 489 63 KF Costed with Errors
3 1.627 0 1.627 117 KF Costed with Errors
2 7.502 0 7.502 381 KF Costed with Errors
1 914 0 914 90 KF Costed with Errors

Looks like 12 materials have been costed overall without error. But this is not the case. 12 materials on level 7 have been costed without error. But there are more materials that have been costed without error, if I go to "Material Overview", on a different level. But these materials are not shown on tab "Costing levels" with status KA Costed without error.

Is that a bug, should I open an incident to SAP?

Thank you,
Joachim
