Many times it happens so that we have to maintain translations for some objects that are already released. So if you go and maintain the translation in whatever language you have to maintain and save the translation, you will not be prompted for any transport request to carry these translations to any other system.
So the dumbest method that one can follow is go and do some dummy changes to the translation object and save it in some transport request and again revert the changes back to whatever it was earlier.
In most of the companies we have custom developed tools to maintain translations then the issue comes what objects were translated and where to find the objects?
SAP has given a very simple and quick way to collect all the translations in a transport where you don’t need to know what objects were translated and no need to search for these objects.
Using TCode SLXT which is used to capture all the translations objects done using SE63.
