No cost estimate found in CK86_99 though material was costed in CK13N

Hello,

We can see that the material was costed in CK13N (date 30.05.2009), but if we check transaction CK86_99 and enter the necessary parameters (all correct: material, costing variant, plant, costing date), the system displays error saying "No cost estimate found".

Thanks in advance.

Regards,

Peter
