Depreciation after an Asset split

Using:

E1 9.1.5

I processed an asset split on P1204, Fixed Asset(FA) 1 into FA 2 and FA 3.

I also manually entered the 2 new FA numbers.

I used the A Method (Amount) to allocate the cost.

This is an existing asset from 2003, so I understand the prior year posting in 12/2017.

In the Cost Summary, I noticed the subledger field has the FA number from the initial asset, FA 1.

When I run Compute Depreciation, its processed using FA 1 as the subledger and not the newly assigned FA number.

When I review the g/l account for the depreciation postings it is also tied to FA1 in the subledger field.
