Importing into Standard Cost Adjustment Entry?

Hello all,

I need to change A LOT of items' standard costs, I was trying to look for a way to import into the Standard Cost Adjustment Entry table via VI job, but didn't see this table available?  Can anyone let me know what the name of this table is?

Also, I will need to change the valuation methods of a bunch of items from Standard Cost to FIFO, is IM_ItemValuationSelection the correct table to import into for this?

Can someone please advise.  Thank you!
