Efrain,
Not exactly sure your requirement, however there is a transaction code PC00_M99_DKON which will show you the wage assignment. On the selection screen enter your country code as 10 if running for USA and the wage type. Execute it.
When you run it for a particular wage type and expand the results 'source system' then you will see the associated Company code for which the wage type is applicable.
Hope it helps you.
Thx,
Ashish
