Custom Sub Ledger Accounting Method not appearing in LOV while creating Ledger

Hi Team,

I had created a Custom SLAM "XXX_Accrual" by copying from "Standard Accrual". While creating SLAM, i have given COA as "XXX_ Acc Flexifield".

When i try to create a Primary Ledger, this SLAM is appearing in LOV whereas when i try to create a secondary ledger, this SLAM is not appearing in LOV,.

Any reason why custom SLAM is appearing while creating Primary Ledger and not while creating secondary Ledger?

Regards,

Arvind
