Thanks for the reply Inna.

Basically I wanted to redefine the project level parameter, so that the the new value for project level parameter should be available for all build configurations in the project.

We have one build configuration (build1) that does few things and creates a new directory with the name as timestamp (e.g. timestamp1), in svn everytime it is run.

Now there are several (about 30) build configurations in the same project that has its svn checkout directory configured as the value for a project level parameter (parameter1) so that checkout happens from the newly created directory on svn. Currently we manually update the project level parameter (parameter1) with the new timestamp (timestamp1) and then run the remaining builds (about 30). I was wondering if we could automatically update the project level parameter (parameter1) with the new timestamp everytime build1 is run. (may be with teamcity api). so that the new timestamp is available to all build configurations (about 30) for its checkout.

Please ask me if something is not clear.

Thanks,

Kumar
