SmartCompaire does not connect to Oracle directly. There is no live connector, scheduled pull or SFTP drop. You export pay results from Oracle, for example as a payroll register, a BI report or a SQL extract. Then you upload the file, paste the rows or type them in.
There is no Oracle-specific parser, so reshape the export into the pay data template, which you can download from the pay data step. The first non-empty row is read as the header, so remove any title rows above it.
Columns are matched by how their names end, such as <system>-PayCode or <system>-Amount. Delete or rename extra Oracle columns whose names end in a template label: Assignment Number would fill the Number column, and Hourly Rate would fill Rate.
Oracle can be the source, the target, or both, as in an E-Business Suite to Oracle HCM Cloud move. SmartCompaire needs the two pay files in its pay data layout, plus the employee and paycode mappings described below.
