Hi Alexander,
I'm facing the same problem here and very happy to see that anybody did it!
I have some questions:
1 - Did It work for the 550 product category?
2 - Did you set the Effects of the Update Types on the Position Components for the update types v380 and v381? If not, wich update type have you assigned to the PCC 1025?
3 - In your scenario do you have to post amortization for costs wich were not payed in the very begining of the transaction, but things like fees that you have to pay along the transaction's lifetime? In that case, how did you solve this situation?
Regards,
Ivan Maia.
