Why more than one transport request is required sometimes?

Once your client is set up in a manner that you have to record customizing changes then a customizing request for the data itself is required and during activation for customizing. In the first screen of the guided activity, you need to enter the transport request for the data set. For customizing it, you would be prompted by the system to enter the transport request and before the activation, it gets generated. You can here make use of the same transport request. A workbench request has to be entered on the activation screen for these settings once the cross-client settings are created by the implementation tool.
