APPLIES TO:

SYMPTOMS

All Resource and Overhead Variances charged to Material Variance Account.
All PREVIOUS level variances are added and charged to material variance account.

CAUSE

If account summarization is switched on then cost elements having same valuation account will be merged in one line only.

Cost Transfer and Distribution to the General Ledger

All costs are maintained by cost element.  If you assign a different account to each cost element as you define your sub inventories and WIP accounting classes (if you use Work in Process), elemental account visibility is maintained when transactions are processed.

If you are using Standard Costing and assign the same account to more than one cost element, you can choose to have the values of these costs elements summarized before being transferred to General Ledger by setting the CST:Account Summarization profile option to Yes.  You can also choose to have elemental visibility maintained by setting the CST:Account Summarization profile option to No.  

If you are using Average Costing, elemental visibility is maintained regardless of how this profile option is set.

If the issue is related to variance lines, all previous level variances go against material variance line only.  This is standard functionality.

SOLUTION

Evaluate the best value for the CST:Account Summarization profile option.
