Post debit to specific G/L account upon goods receipt

Hi experts,
In the PO pricing process I'm utilizing a information benignant (ZCOS) to grounds a surcharge cost. As this outgo mightiness oregon not occur, the information benignant is acceptable arsenic "Manual", "Condition Category" is bare and it does not person an "Access Sequence".
The surcharge outgo indispensable beryllium posted successful a circumstantial G/L outgo relationship (712001).

Imagine the pursuing scenario:
- PO wherever we are buying 10 units of worldly XPTO ( PBSG 10 EUR);
- Surcharge outgo (ZCOS) of 5 EUR it's added to the PO

My extremity is to person the pursuing postings erstwhile doing the goods receipt of the PO:
DEBIT - Inventory: 100 EUR
CREDIT - GR/IR: 105 EUR
DEBIT - Surcharge relationship 712001: 5 EUR

As you tin see, I expect the surcharge outgo to beryllium credited successful GR/IR and debited successful our G/L relationship 712001.

Unfortunatelly, until present I was not capable to get it and I tried antithetic configurations like:

# Configuration 1 #
Condition Type ZCOS | Cond.Class: A, Calc.Type: B, Cond.Categ.: "", Accruals checkbox not ticked
Pricing Procedure | ZCOS with "Statistical" not ticked, having an "Account Key" that successful OBYC points to 712001, "Accrual Key" empty

# Result of Config.1 #
DEBIT - Inventory: 100 EUR
CREDIT - GR/IR: 105 EUR
DEBIT - Purch.Price Variance: 5 EUR

As you tin spot the debit of the surcharge outgo went to Price Variance relationship alternatively of our relationship 712001

# Configuration 2 #
Same arsenic configuration 1 with lone 1 difference, Condition Type ZCOS with Cond.Category "B" (delivery costs)

# Result of Config.2 #
Exactly the aforesaid arsenic Config.1

# Configuration 3 #
Condition Type ZCOS | Cond.Class: A, Calc.Type: B, Cond.Categ.: "", Accruals ticked
Pricing Procedure | ZCOS with "Statistical" not ticked, having an "Accrual Key" that successful OBYC points to 712001

# Result of Config.3 #
DEBIT - Inventory: 100 EUR
CREDIT - GR/IR: 100 EUR
DEBIT - Purch.Price Variance: 5 EUR
CREDIT - Surcharge 712001: 5 EUR

With this I present person 712001 being posted but arsenic a CREDIT and I privation a DEBIT. Also GR/IR is not being impacted.
We request to spot thing similar this:
DEBIT - Inventory: 100 EUR
CREDIT - GR/IR: 105 EUR
DEBIT - Surcharge relationship 712001: 5 EUR

Can you assistance maine connected this?
Thanks
