T Code - CJ9FS
Co versions are used when the various cost estimates are to be prepared and the best co version has be selected. In this case the last co version becomes activated.
My understanding is as below
a.The project created has a base co version as 0
b. Then create i.e. say three versions as 1a, 1b and 1c from the cost perspective and select the best one.
c. Then convert the best version into the version 2. Now this version 2 is the active co version of the project.
Is it correct or is there any other purpose of the co version.
If this is correct then my question is that
1. What is the difference between the co version and the simulation version.
Thanks in advance
A project does not have a base CO version. But while a cost planning is done automatically, the values appear in CO version 0. In case you carryout manual cost planning, CO version defaults to 0 on the first screen of manual cost planning transaction.
CO version is only for cost planning. Simulation version has a lager application. It is creating a different version(s) for the project itself. Here, various parameters of the project are changed and managed. Out of multiple simluated versions of the project best one is selected for actually executing a project.
