Q). In the SD module, what are the three levels of a sales document?

Answer:

In SAP SD, each sales document has three main levels and each level is represented by a table that holds the data for that level. The data for the header level of the sales document is stored in table VBAK. Data for the item level is stored in table VBAP, and data for the schedule line level is stored in table VBEP. Thus, for a sales document, diiferent levels of data are stored at various levels.
