Summary

0029729: Differences between actual cost and standard cost (variances) should not trigger Cost Adjustments.

DescriptionDifferences between actual cost and standard cost (variances) should not trigger Cost Adjustments as the "Total Cost" and the "Unit Cost" of a transaction should not change.


Steps To Reproducen/a

Proposed SolutionDifferences between actual cost and standard cost (variances) caused by
- purchase price differences
- backdated transactions
- negative stock correction
- and manual cost correction if any,
should not trigger a cost adjustment transaction.

Above implies that:
- the "Total Cost" and the "Unit Cost" of a transaction valued at standard cost must not change.

- no cost adjustment transaction is created for products valued at "Standard Cost".

- there are some scenarios for which variances can happen even in the case of products valued at "Standard Cost", that is "purchase price differences".
Those variances will no trigger a cost adjustment but would need to be posted to a "PPV" account. For additional information see issues below:

- purchase price differences - issue 29728

Finally,

Inventory amount update - this one is working ok for standard as it creates two physical inventories (closing & opening) which posting is correct. In fact this process is the one to use to change the standard cost of a product.

 When programming the software we should be aware that there are more types of variances than only PPV.

In general, variances occur when there is a difference between the standard and actual costs and this relates to purchased and manufactured goods.
(Implicitly -> variances do not occur when using average costing).
So instead of coding directly towards a PPV, it would structurally be better if the software would be prepared to handle different causes of variances:

·Differences with actual costs coming from purchase invoices - PPV

·Differences with actual costs coming from landed cost invoices - Landed costs variance

· Differences with actual costs coming from manufacturing (work order postings) can have several causes and should be recognized individually:

o Usage variance –> when a different/substitute material was consumed

o Material variance –> when a different qty of the same material was consumed

o Method variance -> when a different routing/machine was used, could have caused 0 cost-difference

o Labor variance –> when a different qty of hours was consumed.

Additionally, if would be good if we could show the cost-element / sub-element that is affected by the variance (can be multiple).

COST ELEMENTS

1 Material = the costs of acquiring (manufactured or purchased) 1 unit of the material.

· SUB ELEMENTS – Only applicable in case of “Landed costs”, and if a) purchased b) specific IncoTerms.

· Duties

· Freight

· Insurance

2 Labor – only manufactured goods. Costs of salaries of direct labor

3 Overhead – Costs of all indirect services: renting of building, salaries of indirect personnel, etc.

4 Burden – only manufacturing - Costs of electricity, water, etc. directly related to the processing of the material.

5 Subcontracting - only manufacturing - Costs of outsourced sub-processes

 Differences with actual cost coming from manufacturing - Not implemented yet.

Differences with actual costs coming from purchase invoices (price differences) - Implemented. See issue 29728 - verified it is working properly.

Differences with actual cost coming from landed cost invoices - Implemented. See issue 29723 - Verified it is working properly.

Backdated transactions scenarios does not imply the creation of any cost adjustment when working with products under Standard costing algorithm.

Negative stock correction does not imply the creation of any cost adjustment when working with products under Standard costing algorithm. See issue 29702.

Not possible to manually adjust transactions valued at standard cost. Verified. See issue 29730

The check of Standard Algorithm in CostingServer should be done after check if landed cost need to be processed
