GL Ledger Flexfield not created

Hi,

we are facing the below issue in oracle isetup.

We have migrated Chart of Accounts from source instance to target instance using isetupafter migration, when we query for the COA in target instance, we are able to find it in Accounting Flexfield, but in GL Ledger Flexfield we are not able to find it.

Sequence of steps:
1. selection of a Chart of Accounts from source instance
2. Extraction of Chart of Accounts from source instance
3. Loading of COA into Target Instance
4. In Target Instance COA is appearing in Accounting Flexfield only but not in GL Ledger Flexfield.

Please let us know how to create GL Ledger Flexfield in target instance??
