Chart of Account

Hi All all of You

How we manage Materials variance Account(For item )

When we create Goods receipt Purchase order then three gournal ledger hit.

1.materials & consumable Debit A/c

2.good received not invoiced Credit A/c

3.materials variance Debit A/c

what is the role of Materials varience G/L

in witch time materials variance G/L will be Credit after Goods receipt ???

And same materials & consumable G/L will be Credit after Goods receipt ???

Because at the time of invoice only good received not invoiced G/L Debit and vendor account Credit

Can we take materials & consumable as a individual raw materials A/c .for total information of raw materials(Price)????
