Debit Memo not creating while perform the returns through RTS interface

Hello,

we are having issue to process the debit memo while returns.  The debit memo gets created successfully if we perform the return through manual return form however the returns created through receiving interface it's not processing the debit memo.

Verified the supplier setup and PO.  We use the same PO for RTS as well on the return form.  Do you have any advice why system doesnt not proces the debit memo?

We have hundres of receipts and returns using the RTS process which is hitting our invoice reconcillatio.

regards

Madhu
