my actual scenario is as below:
I have Ztable 'X' in SAP DEV-> QAS->PRD it has less data in DEV and QAS system but almost 8,00,00,000 in PRD system.
Now we want to make a clone of this table with table entries in DEV->QAS->PRD system.Once this New table will have 8,00,00,000 records we will schedule a job to Update the new table from the Old table.
Only Problem is how to Upload 8,00,00,000 records in New table in Production in efficient way.
