CPQ --- Format Return BML Constraint

Summary:

Error on format return BML Constraint Single Select Picklist.

Content (required):

Hello,

we need to create a "constraint" where the action attribute is a single picklist. Inside the BML we want to return the tuple of the records to be displayed but the return format seems to be invalid.

We tried with:

- A ~ B;

- A | B;

- A [A] ~ B [B];

Thnks a lot
