Item Posting Profiles (Cost change variance) And (Rounding variance)

(0) ShareShare
ReportReport
Posted on by 605

When trying to report a BOM item as finished, I'm getting 4 lines in the ledger voucher with posting types (Cost change variance) And (Rounding variance) 2 lines for each with total balance = 0.
I can't tell why those lines are being generated.
I've read something related to Cost change variance that says: If quantities are transferred across sites where the costs differ, a cost change variance would be posted. Also, a return order may result in a cost change variance if the active cost has changed since the original post.

In my scenario, The item cost is activated by Site. When posting the BOM Journal, the items are posted with Site (Same site of the cost price) and warehouse.
I've tried to activate item cost price by site and warehouse, but I couldn't as the warehouse is disabled on the cost price form. After adding it by code and trying to report the item as finished, the for lines are not generated.
In real life we don't have Cost change variance when dealing with items accross different warehouses under the same site.
Can someone please help to explain the use of those two posting profiles and how to avoid getting their lines generated?

Installed Version: Ax 2012 R2 CU6.

    Hi Ihab,

    Are you using the Standard costing method? Then differences are calculated and posted accordingly. You mention the lines have total balance 0. Can you indicate if the accounts are different?

    Usually when you have BOM items at a cost of $ 5 each. You need 4 of them to create 1 new product. The product cost is set to $ 21.

    In this case the $ 1 difference is posted.

    Could you share the created transactions?

    Dear Andre,

    Thank you for your reply.

    I'm using the Standard costing method for all the items. In my scenario, I have 3 items to create 1 new product. I've used the item cost form for the components and used calculation for the cost of the new product (the cost is correctly calculated with no difference). Kindly find below the details of the scenario

    Item 1 Cost: 4000
    Item 2 Cost: 6000
    Item 3 Cost: 500
    New product calculated cost: 10500

    Reporting 1 item of the new product as finished results with the following voucher

    Posting type Main account Account Name Debit Credit
    Rounding variance ?? ????    10,500.00                   -  
    Cost change variance ??? ??????                   -      10,500.00
    Rounding variance ?? ????                   -      10,500.00
    Cost change variance ??? ??????    10,500.00                   -  
    Production offset account receipt 725510 Inventory variance of Finished Goods                   -      10,500.00
    Production receipt 371155 Inventory - finished goods    10,500.00                   -  
    Production offset account issue 615110 Inventory variance of raw materials      4,000.00                   -  
    Production offset account issue 615110 Inventory variance of raw materials      6,000.00                   -  
    Production offset account issue 615110 Inventory variance of raw materials          500.00                   -  
    Production issue 311110 Inventories - raw materials                   -        4,000.00
    Production issue 311110 Inventories - raw materials                   -        6,000.00
    Production issue 311110 Inventories - raw materials                   -            500.00

    As stated previously, when trying to add the costs manually by an x++ job with site/warehouse inventdim combination, the highlighted transactions are not getting generated.

    Thank you for your help,

    I see the same behaviour - it seems to be the standard way for AX to handle BOM journals under standard costing.

    What I tested is that rounding variance postings will always balance out, no matter what you do (whether you consume items according to BOM or not). However, cost change variance will reflect actual variances. My example:

    I had a BOM for 2 lines, one item had a standard cost of 230, the other - 340. The finished good had an according standard cost of 570. I then processed a BOM journal with only 1 consumption line (the one for 340). What I got was:

    a) 4 lines of Rounding variance (+340, -340, +230, -230) all balancing themselves out

    b) 3 lines of Cost change variance (+340, -340, -230) resulting in a net -230 cost change variance (correctly, since I consumed less than needed so the variance is on the credit side).
