Operating unit not available on Receivables - system options screen

Hi ,

I did the following setups in General Ledger and I am unable to see the Operating unit in the Receivables System Options window for me to setup the OU for receivables.

1) Setup a new ledger and assign a new operating unit to it.

2) Add the operating unit to Security profile in the HRMS and use the Security profile and assign to a receivable responsibility

3) Also added the ledger in the ledger set that is associated to the receivable responsibility using GL: Data Access Set profile option.

After all this, I am unable to view my Operating unit in the Receivables System Options window.
