Subject Re: Clarification on Validator Classes for Multiple Rescheduling of a Loan
Date Tue, 12 Jul 2016 11:10:16 GMT
Dear Adi and the team,

As you may know Vishwas from Conflux Technologies has finished the
development of Mifos fix that solves the rescheduling issue. We will do
in-house testing for the coming days.

Can you please let us know when this could be implemented into Mifos update?

Regards,

Andris
