If you have defined a cost code standard and cost code level for a project quotation, you can define a cost code for each WBS line. If the cost code level is Transaction, you can also define a cost code for each estimated-costs-and-revenue line. So, estimated-costs-and-revenue lines of one WBS line can have different cost codes.

Standard procedure

1.	Click Advanced project management.
2.	Click Project quotation.
3.	In the list, click the link in the selected row.
4.	Click Advanced WBS.
5.	Click Edit.
6.	Select a task having estimate lines.
7.	Click the Estimated costs and revenues tab.
8.	In the list, find and select the desired record.
9.	In the Cost code field, enter or select a value.
	Note: You can only change the cost code on an estimate line if the default cost code level is set to Transaction. You can do so, on the root project node. You can also change the default setup in Advanced project management parameters.
