Using Update data action to update data in job data component

Question

hi, I'm trying to update data in job component using CI_JOB_DATA, im setting action as updatedata. but i'm getting error.
"UPDATEDATA - updating existing keyed child records
Example - updating an existing row of data by using the key value(s) and enough child fields to single out the distinct record. "
Is the above statement correct?

Answer 1

For example ExceltoCi uses ComponentInterfaces to load data.
Snipet from PeopleBooks:
PeopleBooks > PeopleTools 8.52: PeopleSoft Component Interfaces > Using the Excel-to-Component Interface Utility
UpdateData.
Use this option to update specific non-key values that already exist. The system uses the keys to locate the row, and when a match is found, the row is updated with new data. If a key match is not found by the system, it displays an error message indicating which collection was missing a key match.
When using the UpdateData action, you must provide all keys for the collection for the system to modify the data.
Note. If you want to insert an effective-dated collection at Level 1 containing a child collection at Level 2, you may need to use UPDATE to insert the parent row at level 1 and then use UPDATEDATA to insert the child row at level 2. This is because child rows are copied forward from the current effective-dated collection as a result of the insertion of a new effective-dated parent row. These child rows will be updated by the component processor with the new effective date, and may have the same level 2 keys as the Level 2 child row that you are trying to submit from ExcelToCI.
