'RCUC' Account ID wrongly picked while applying receipts to invoices

Hello Team,

We have got following issues in  production environment.

Case :-

1. User created an unapplied receipt of $ 60,185/- for a customer having G/L offset 'ITR' which created batch RB / 6307912 which was kept unposted for 2 days.

2. The same unapplied receipt was applied to invoices for two different customers (same customer having G/L offset = 'ITR' but setup as different address book numbers) having same G/L offset i.e. 'ITR' which didn't create new batch as the batch RB/ 6307912 was not posted.The batch RB/6307912 was posted successfully.

3. During the application of unapplied receipt to invoices it has been found that account ID against G/L offset 'UC' was picked instead of account ID setup against 'ITR' which is reflecting in F03B14 on file line identifier no line no.18.
