Keep working on BWV 1013.
It's really a Partita in Sonata form.
If you read the description below you will see that it's a synonym for suite (a collection of dances). All of the movements for the Partita are named after, and written in the style of dances of the Baroque Suite.

"Partita was originally the name for a single instrumental piece of music (16th and 17th centuries), but Johann Kuhnau and later German composers (notably Johann Sebastian Bach) used it for collections of musical pieces, as a synonym for suite.
"
The defining factor is that the BWV number 1013. Bach may have written a Sonata in a Minor but the Bach Werke Verzeichnis number would have invariably been different.
