Creation of Transformation File

Hi Experts,

I am new with BPC 10 NW and therefore needed your little guide to create transformation file :

I need to map (Account, Category, Currency, Time & Signed Data).

Account = PL310,PL320 & PL330

Category = Actual

Currency = LC

Time = 2014.01 to 2014.12

Signed Data = 10,000 for period one, 20,000 for period 2 and goes on till 120,000 for period 12.

Please guide me what to write below MAPPING and CONVERSION in order to map my imported data through Business Process Flows?

Thanks in Advance !!!!!

Regards,

Zain Bashir
