How is 0VTDetail populated in 0PC_C01

Hi,

I need 0VTDetail (Details of Vlaue type) values for some RKF in query.  I see the infoObject in 0PC_C01 cube but it is not mapped from datasource 0CO_PC_C01.  Transformation has a blank routine.

Does any one know how it is populated.  What is the source field in ECC.  I tried to look in COSP, COSS AUFK and other controlling tables but could not find any that maps to it.

Any help is greatly appreciated.

Thanks
