Relationship in the field value of F0411.PST and F0411.POST and the creation/update in F0414

Can we find any relationship in the field value of F0411.PST and F0411.POST and the creation/updating in F0414?

I need to create custom info for AP Payment and would like to know if I can just use F0411 for the data selection in F0411.PST = 'A' - Approved for Payment and F0411.POST = 'D' - Posted for certain DDJ - Net Due range and not use F0414.

Will F0411 fields value get updated when system create or update F0414?  If yes, what fields will be updated?

Thanks to share your expertise,
