Stupidedi::Exceptions::ParseError: required segment SE is missing from table Table 3 - Summary

[n4a4]

I have a block of code that is writing a purchase order (850). I call builder::CTT to try to write the count of the orders but when the line of code is included, I always get the following error:

Stupidedi::Exceptions::ParseError: required segment SE is missing from table Table 3 - Summary

However, when I remove the CTT line it always works. Am I using this in an incorrect way?

This might be a bug in stupidedi. Can you change your example to include literal values (rather than references to hash values) that I can paste to help me debug? Let me know if you need a quick workaround in the meantime, but I do want to figure this out and hopefully fix it.

Having the same issue here.
Changing CTT in the transaction_set_defs to Mandatory fixes the parse error.
