Invoice & credit memo

Question

hi all,
i understand from forum that :
Invoice / credit memo - GR/IR clearing account and vendor account
qty and value will give impact to GRC
Subsequent credit/debit - Stock account and vendor account
example of credit memo :
Credit memo is posted when there is u want to correct the invoice posted already for both qty and value.
For eg if vendor gives u invoice of 12 qty and value 120. but actualy he delivered only 10 qty of 100 rs. so in this case u post the credit memo with 2 qty and 20 rs so the total invoice u post becomes 10 qty and 100 rs.
above i clearly understand.
but when i check my system on miro posting and po history in me23n, is different case.
GR  - qty 20080 value  3950
IR - qty 20080 value 3950
after vendor invoice is posted, there is a credit memo and invoice, both with reference to PO.
credit memo qty 20080 (same qty) value 1000
credit memo, the entry is dr vendor cr prd
invoice qty 20080 (same qty) value 1000
invoice, the entry is cr vendor dr prd.
1) may i know why the offsetting account is prd? when i see in miro, no GL tab but only has po reference tab.
2) where does the setting to ask system to use prd?
thanks

hi,
i can understand your reply.
but why the treatment is different from the general understanding below:
Invoice / credit memo - GR/IR clearing account and vendor account
Subsequent credit/debit - Stock account and vendor account
if
GR - qty 20080 value 3950
IR - qty 20080 value 3950
Kindly verify if below 4 points are correct.
after invoice posted, if i do credit memo reference to the same PO,
1) qty remained the same 20080 and value is less, say 1000, this 1000 is posted to credit prd?
2) if qty say, 1000 and value 1000 also, double entry will be hitting GRC?
after invoice posted, if i do invoice reference to the same PO,
3) qty remained the same 20080 and value is less, say 1000, this 1000 is posted to debit prd?
4) if qty say, 1000 and value 1000 also, double entry will be hitting GRC?
thanks
