Question on interface for FB50

Question

I am new to the ABAP world and a little confused on the interfacing of FB50. we currently have a ABAP process that reads a text file and submits the G/L data using FB01 and RFBIBL00. We would like to start using FB50 and I am reading that this is a enjoySAP transaction that does support batch input. I am also reading about interfaces to FB50 that use the bapi BAPI_ACC_DOCUMENT_POST and/or  BAPI_ACC_GL_POSTING_POST. Can I write a ABAP to read the text file and use one of the BAPI's to load data to the FB50 transaction? We would like to separate our loading processes so that we can use FB50, FB60, FB70 and move away from FB01 to load all of our data.

Submitting as background job:

Scheduling a submitable program as a background task with the number number in a background request name. After scheduling, the background task is completed by function module JOB_CLOSE and released immediately.
DATA: number TYPE tbtcjob-jobcount,
      name TYPE tbtcjob-jobname VALUE 'JOB_TEST',
      print_parameters TYPE pri_params.
CALL FUNCTION 'JOB_OPEN'
