Thanks Ravi, I have seen the above link and that means I should not set CM_DISABLE_BUILD_REUSE to pipeline.
There is no variable set to pipeline and if I try to redeploy the same code multiple times without changing code, it is still doing build and unit testing -> deploying to environments.
Can you please suggest me how to avoid multiple times building the same code and just deploy the code.
Thanks & Regards
Veera
