We are trying to move the development component from Dev Track to Cons Track for making a release to QA. As process of which we tried to import the DC which failed and we realized that it failed because we didn't have the sap.com SCA's imported. Now while importing the SCA's by mistake we imported a wrong level of SCA, and when we try to import the right level SCA it is failing. Do we have to remove the older level SCA's first if yes how do we do that? If not any insight on why its failing would be appreciated.
