You use the 
Suggest
Item Standard Cost batch job to create suggestions for changing
the costs and cost shares for your standard costs on the item card.
The items can be end items or they can be components in a
production BOM. When the batch job has been completed, you can see
the result in the Standard Cost Worksheet window.
This batch job only creates suggestions. It does not implement the suggested changes. If you are satisfied with the suggestions and want to implement them, that is update them on the item cards and insert them in the Revaluation Journal, you can use the Implement Standard Cost Change batch job. The Suggest Item Standard Cost batch job is found under Functions in the Standard Cost Worksheet window.
When you implement the changes from the Standard Cost Worksheet, you also update the standard cost on the SKUs.
If you want to include more information, you can select additional fields to be included in the batch job. To do this, in the Field field, press F3, click the AssistButton and then select the relevant field(s). You can set filters on any of the fields. If you do not set any filters, the batch job will include all your records.
Click OK to start the batch job. To filter the information in the batch job, fill in the relevant fields as follows:
No.: Enter the numbers of the items to be included in the batch job. Click the up-arrow in the lower left-hand corner of the window to see the table with the results of the filters you have set for the batch job.
Vendor No.: If you want to change standard cost for one particular vendor, this is where you can specify the number of the vendor to be included in the batch job. To see the existing vendor numbers, click the Filter field, then click the AssistButton that appears to the right.
Replenishment System: This field will be filled in with the default value of Purchase.
Costing Method: By default, this field is filled out with Standard.
Standard Cost: Enter the adjustment factor you want to use to update the standard cost. You can also select a rounding method for the new standard cost. Note that you have to fill in the field using a decimal for the percentage increase, for example 1.1.
Indirect Cost %: Enter the adjustment factor you want to use to update the indirect cost %. You can also select a rounding method for the new indirect cost %. Note that you have to fill in the field using a decimal for the percentage increase, for example 1.1.

This batch job is intended for purchased items. If you want to update an item with a production BOM, you must first fill in the worksheet with all the components and then run the Roll Up Standard Cost batch job afterwards.
