Standard Cost on Business Central for Manufacturing

(6) ShareShare
ReportReport
Posted on by 197
Hello
I am slightly new to standard costing on manufacturing on business central so please bear with me as I have the following questions.
 
1. If a Released Production Order has been modified to use a different routing or say add an additional item or say decide to use a contractor on a routing step, how does the standard cost adjust to take that into account or does it adjust at all? For example, if a different routing is used, how can the standard cost be modified to take that into account?
 
2. The Cost Share on an Item does not match the Standard cost amount on the item card. Is the Standard cost on the item Card based on an average and does it include revaluations? Where can I actually view the real/latest standard cost that has been loaded against the item card? I am looking at this from a finished good perspective.
 
3. We often have a situation whereby we use a subcontractor during busy periods for some of our manufacturing operations. I was wondering whether it is optimal to create separate routings for where the subcontractor might be used and or should we just change the production order as and when we require the subcontractor (which would be a lot during a busy period but not always). Having a routing created means it's less work to configure on the system and it's more automated but the answer depends on whether standard costing is affected (for calculating variances) and also what is the optimal solution.

    1. Does standard cost adjust when a Released Production Order is modified (routing changes, extra items, subcontractor added)?

    • Standard cost is fixed once calculated and loaded on the item card. It does not automatically adjust when you modify a production order (e.g., change routing, add components, or subcontract a step).
    • Variances are used to capture differences between actual and standard cost

      • If you add a subcontractor or change routing, the actual cost posted will differ from the standard cost, and this difference will appear in variance accounts.
    • To reflect new routing or subcontracting in standard cost:

      • Use the Standard Cost Worksheet to recalculate and update costs. This process considers BOM and routing changes, including subcontractor costs, before certifying the new standard cost.

    •  

    2. Why does Cost Share differ from Standard Cost on the Item Card? Where to see the latest standard cost?


    • Cost Share shows the proportion of cost elements (material, capacity, subcontracting) in the BOM/Routing structure, not the actual standard cost on the item card.
    • The Standard Cost on the Item Card is:

      • Based on the last certified calculation (not an average).
      • It does not include revaluations; those affect inventory valuation but not the frozen standard cost.

    • To view or update the latest standard cost:

      • Navigate to Item Card → Costing Method = Standard → Unit Cost field
      • For recalculation, run Calculate Standard Cost (choose All Levels for BOM roll-up) and update via the Standard Cost Worksheet

    3. Subcontracting during busy periods: Separate routings vs. ad-hoc changes?


    • Best practice: Create alternate routings for scenarios where subcontracting is common (e.g., busy periods). Why?

      • Easier to manage and automate purchase orders for subcontracted operations.
      • Maintains consistency for planning and costing.

    • If you only occasionally subcontract, you can modify the production order routing manually, but this is less efficient.
    • Standard costing impact:

      • Subcontracting costs are part of the routing cost structure. If you frequently subcontract, include these costs in the standard cost calculation for accurate variance analysis.

    • Setup tips:

      • Create a Subcontract Work Center linked to the vendor.
      • Define cost basis (per unit or per time) and lead times.
      • Use the Subcontracting Worksheet to automate PO creation for subcontracted steps.
     

    ✅ Summary Recommendations


    • Standard cost is static until recalculated; variances capture deviations.
    • Use Standard Cost Worksheet for updates after BOM/routing changes.
    • For subcontracting:

      • Frequent use → Alternate routings for automation.
      • Occasional use → Manual routing edits.
    • Always run cost roll-up for all BOM levels to ensure accuracy.

    Varaince is when there is difference in Purchase cost and Standard Cost.
     
    Below links helps how variance is considered and when . 
     
     
     
    In your case if you want to update Standard Cost you can refer the below link which updates  Standard Cost

    Hello,
     
    Standard cost never updates from changes on a released production order. Any routing/BOM/subcontractor changes there only create variances. To change standard cost, you must update the routing/BOM, then Calculate + Revalue Standard Cost. Cost Shares don’t always match the Item Card because they show a structure breakdown, not posting history or averages. For subcontracting, separate routings are the correct approach—otherwise you’ll generate constant unfavorable variances and lose meaningful cost analysis.
