Which BW objects should be used in 0FIGL_O14 for MENGE and MEINS fields.

Hi,

I'm trying to load data from fields MENGE and MEINS to 0FIGL_O14. They can be seen in 0FI_GL_14 data source.

The problem is I don't know which BW objects should be used in 0FIGL_O14 for those fields. Should they be created ?
