If you want to use cost codes in your project quotations and projects, set the default cost code standard and default cost code level.

You can change these defaults on a project quotation work breakdown structure. Note: If you change these settings on a project quotation work breakdown structure, and already cost codes are defined, these are lost.

Standard procedure

1.	Go to Project management and accounting > Setup > Advanced project management > Advanced project management parameters.
2.	Click Advanced project management parameters.
3.	In the Default cost code standard field, enter or select a value.
4.	Define the default cost code level: - Activity: You can define a cost code for each WBS line. All estimated-costs-and-revenue lines of a WBS line have the same cost code, which cannot be changed. - Transaction: You can define a cost code for each WBS line and for each estimated-costs-and-revenue line. So, estimated-costs-and-revenue lines of one WBS line can have different cost codes.
	In the Default cost code level field, select an option.
5.	Click Save.
6.	Close the page.
