Document Sequence Category Override at Payables Invoice Header Level

Content (please ensure you mask any confidential information):

Hi All,

We have a requirement to change the Document Sequence Category defaulted at the Invoice header level. The below prerequisites were done.

1. Ticked 'Document Category Override' at 'Manage Invoice Options' Configurations
2. Document Category was created and assigned to table 'AP_INVOICES_ALL' at 'Manage Document Sequences Categories' configuration
3. Document sequence was defined with the type of 'Manual' in the 'Manage Payables Document Sequences' configuration.

However, the system doesn't allow to change the document category in the Invoice header level.

Please Advice.
