POSDM: Change Transaction using BAdI

Hi Experts,

We have a requirement, once we receive the data into the workbench, a task is associated to the transaction. Say task is Z001, when we execute the task, we need to change the data in the transaction at line item level using the code. Can you please let me know the BAdI that will help change the data in TLOGF?

Thanks,
Suraj Pabbathi
