While configuring NWDI - CMS, under Transport Studio, we need to put SAP-JEE.sca, SAP_BUILDT.sca and SAP_JTECHS.sca files under \usr\sap\JTrans\CMS\inbox. so that these files can be seen in Checked-In tab.
Usually these files can be found under \usr\sap\<SID>\SYS\global\CMS_CBS\plugins but in my j2ee these files are not available.
I downloaded these files from marketplace which are retrieved in .zip format. on Extraction i did'nt get any .sca file. i renamed these file to .sca and put in CMS Inbox but all in vain.
