Release management interface APIs

Hi Friends,

Present we are using RLM demand process through EDI and creating demand lines for customer.

as part of global solution, we are planning turning off EDI and directly insert data into RLM interface tables and process through RLM workbench and create demand lines.

just we are turning off EDI and use RLM by inserting demand into RLM interface table.

Do we have any API insert data into RLM tables ?

Thanks
