Means of transport missing in APO

Hi,

We have created  transportation lanes and means of transports in 2010. Recently we roll out 2 plants in January 2014. Now i can see transportation lanes but means of transportation's are missed. Transportation and means of transportation validity is 01.01.1990 (Start date) - 01.01.9999 (End date). May i know the reason, why those are missing.

Thanks in advance.

Regards,
