Default Ledger value -how to pass in Concurrent Parameter

HI,  We are using R12.

We created a new value set  - XX_Ledger_LOV  from  GL_Ledger Table

We attached  this value set to a Concurrent program parameter.

When user running the concurrent program, for the parameter displaying  ledger  values from the  table for selection

But we need to pass value - such way LEDGER NAME  automatically passed by his responsibility.

For Example fro  Organization  selection  we can use in where condition  "ORGANIZATION_ID =:$PROFILES.ORG_ID"

But for LEDGER  selection which value to check in PROFILE.
