What is a composite script in CBTA, and how does parameter exchange work in it?

It combines 2+ CBTA scripts into one end-to-end composite test configuration; entry is in Solution Documentation, Test Tool dropdown → Composite Test.

Adding scripts enables parameter exchange — e.g. an FB60 invoicing script outputs a document number in the message bar; expose its export parameter and import it into an FB03 display-document script (both in the composite → can be Local parameters). Composite parameters are defined in the SECATT script (double-click interface CIF1_1).
