We need to re-run custom gl plugin script for existing Customer Deposit Manual process edit-save works but it is huge job and wasting time We tried to trick and created an dummy MassUpdate for one unnecessary field in Customer Deposit record... But result is failed... Fielsd is updated, but Custom GL script wasn't triggered Any idea?

Should get similar result, but maybe try to csv import on the records?

yup. good idea!

Or perhaps move them to a different posting period and then back to force a recalc of the GL posting.
