A prerequisite for entering a text in the sales order is that at least one text type (text ID) exists. The text type is like a paper sheet on which text can be written. SAP delivers text types for the various text objects. However, the customer can also define their own text types in Customizing. Text types are defined for text objects.
The figure illustrates how you maintain text types for text objects.
Note
In general, one text type per text object would be sufficient to enter texts. Since you can enter any number of different texts in one text type. The disadvantage is that you cannot differentiate between the texts with regard to their control. For each text type, you define, for example, whether a text is output on an output, whether and from where the text of a text type is copied, or whether the text is copied to a subsequent document.
Customizing of the texts in the context of the sales document can be found in the SAP Customizing Implementation Guide under Sales and Distribution → Basic Functions → Text Control → Set Up Text Determination. This takes you to the Customizing Text Determination application. This application can also be called directly using transaction code, VOTXN.
