Transporting SapScript Texts created in SO10 can be a mystery. Transport of these texts to other clients is done using program RSTXTRAN (SE38). Here you can attach the text objects to a previously created transport.
If you are wondering what you can use these texts for: you can create dynamic text fields that are used by custom made forms. You can create one standard SmartForm that refers to a text item you created in SE10. When the text in the future requires a change you don’t need a programmer to modify hardcoded text in the order form. You can just modify the text in SE10.
