Unable to Download Check Output in Manage Payment Files

Hello,
We made few single payments for suppliers in Oracle Fusion. Normally, the check output can be downloaded from Manage Payment Files. However, for some of these payments, the check output is not available to download.

Has anyone experienced this issue before?

• The payments show as completed, but the output file is missing.
• Other payments made same day are showing the check output correctly.

What could cause the check output to be unavailable, and how can we retrieve or regenerate it?

Thanks in advance for your guidance.
