ICData parameters

Hi,

  Based on the available documentations, the ICData logic copies data from 'DataSrc.IC_Origine = I' to DataSrc.IC_Origine = C1, D1, C2, D2'.

  How do we tag Accounts as Source Accounts and Destination Accounts for ICData?

  I also have 2nd question.

  Referring to a standard ICData script logic below,

*RUN_PROGRAM ICDATA

CATEGORY=%CATEGORY_SET%

CURRENCY=USD,EUR

DATASRC=INPUT

TTD_RA=%TIME_SET%

ENTITY=%ENTITY_SET%

TYPE='I'.

*ENDRUN_PROGRAM

  What does TYPE='I'. refer to?

Thanks,

LC
