FM CPCC_S_TASK_LIST_MAINTAIN to change CHAORIG fields?

Component Version: EHP7 for SAP ERP 6.0

Hi, all.

I have a requirement to update all PLMK records per Task List Group using a Z program. Is it possible to call this FM to change PLMK fields like CHAORIG and QP_CHAORIG_ID? Apparently, these two fields do not exist in the FM's corresponding INSPECTION_CHARACTERISTICS_X flag table parameter.

I tried to call the fm but it didn't work as I expected. Kindly advise.

Thanks,

Luisa
