All nodes in SAP system have translatoin object type SHI*. For example SAP Object have SHI3 and customer object SHI5.If you know to make an object list in LXE_MASTER, you just have to get the developer package from node and to put it into graph/collection. Then you can make an work list for translation from all nodes from this package. All this activities you are doing in LXE:MASTER transaction, you just need to know how. At the end you will get one list which translator have to translate direct in the system and you just have to transport all this elements (translations text) to the test and productiv system.
