Function /OPT/VIM_START_DOC_PROCESS_EXT with financtial positions

Hello,

Pleas I need to use the /OPT/VIM_START_DOC_PROCESS_EXT function with finactial positions. I am using this Funtion Module in order to post MIRO documents, I need to use Financtial Positions but I don't know how I can do it because I debugg the fuction module /OPT/VIM_START_DOC_PROCESS_ICC and I do not find any code when this FM build the data.

Please if you have any information i will be very grateful.

Best regards.
