How records in JDE table can be updated using Groovy script

Hi

Would like to know, how can we update records in JDE table using custom Groovy script.

Consider a scenario, where an orchestration is designed to extract data (using Data Service Request) and write to csv file (using custom Groovy script).

Is there a way that we can also update a flag in table to mark the record as processed, as we are reading records to write to csv file.

Can we perform an update table operation within the same script which is writing records to csv file.

Thanks.
