Hi,
small remark.
In standard way there is no impact to New GL view, because there in no field CI in faglflex* tables (of cause if you're not on psm* or fm* tables)
According to my experience splitting for CI uses often (apart from on line payment update).
For instance: to build Cash flow with analytic GL+CI, Liabilities wise CIs and so on...
Of cause for that you need to activate splitting, then enhance fagl* tables for Z* commitment item field and so on.
