There is no cost component split for cost estimate &

What causes this issue?

The cost elements for cost estimate &v1& are not assigned to any cost
components. It is therefore not possible to display the cost component
split.
Either you have not saved cost estimate &V1&, or the cost component
layout has not yet been defined in Customizing. If the cost component
layout is missing, you cannot assign the cost elements in the cost
estimate to cost components.

How to fix this error?

If you are creating the cost estimate, save it and select the <LS>cost
component split</> function in the change mode.
If you are changing or displaying the cost estimate, go into
Customizing and assign the cost elements to the cost components.
