What is the Difference b/w

Hi All,

Could any body explain;

1. Valuation Accounts (Material, Outside processing, material overhead,overhead & resource) use in Inventory Organization Parameter > Costing Tab
2. Valuation & Variance Accounts (Material, Outside processing, material overhead,overhead & resource) use in WIP Accounting Class.

Is there any difference between the above two types?

Is it possible to use the same accounts on Inventory Organization Parameter > Costing Tab & WIP Accounting Class.

Kindly suggest it should be the same or different?

Note: Please find attached snaps for details

Regards,
