Standard texts used in SapScript (created with transaction SO10) can be included in transport orders.
You want to transport SAPscript Texts from a source system to the target system. You can do it in different ways. If you want to copy texts within a system from one client to the other you can execute the report RSTXTCPY.
In other cases, i.e. transporting the texts between the different systems, you can use the report RSTXTRAN.
You have to create a Workbench transport order with transaction SE10. When created, click on it, go in menu Request/task –> Object list –> Display object list. Go in modification mode and add a new line with:
PgmID = R3TR
Obj = TEXT
Object name = TEXT,,ST,
R3TR / TEXT / TEXT,YMM_MEDRUCK_MAIN_16_EC,ST,F
