Queries :: Using Count And MIN Together To Retrieve Only MIN Record With Count

I have a table that has 5M+ accounting line entries. Below is an example of one accounting journal in the table.

BUSN_UNIT_IJRNL_DJRNL_ICNCY_CMONY_A
CB0014/07/20140002888269323AUD16797
CB0014/07/20140002888269323AUD-16797
CB0017/07/20140002888269323AUD16797
CB0017/07/20140002888269323AUD-16797

The journal ID above was an accounting entry, debit $16,797 and credit $-16,797. because it was entered as a reversing journal in the system, the table has captured the Journal ID with 2 dates. For my purpose i only want the one date (MIN) date, the total amount of the journal (either the debit or credit amount 16,797) and the total number of lines the journal ID has so in this instance I want the count to be 2 and not 4.

Right now this is what i get

BUSN_UNIT_I JRNL_I CNCY_C SumOfMONY_A CountOfJRNL_I MinOfJRNL_D
CB001 0002888269 AUD 0 4 4/07/2014

This is the output i would like

BUSN_UNIT_I JRNL_I CNCY_C SumofMONY_A CountofJRNL_I MinOfJRNL_D
CB0010002888269323 AUD16797 2 4/07/2014

Im thinking with the total sum because theres debits and credits is there a way to do the absolute value of the journal MONY_A then divide by 2?

current SQL
