JDEW A9.2.1 Related Addresses
This was taken from the documentation on Related Addresses;
Related Addresses are used primarily in conjunction wiht the Send Statement To field (STTO), the Send Invoice To (SITO) field, and the Ship-To or Sold-To Related Address (RLAB), all of which are in the Customer Master file (F0301). Application programs, such as Sales Order Processing and Purchase Order Processing, use the code located in one of those three fields to locate the related address to be used in the application.
So here is my question, since these fields are in the Customer Master how would they be used in Purchase Order Processing?
