I have SharePoint list form which is passed with URL params (PIID and CCID) which consists of Primary keys (Unique Identifiers) from two other SharePoint lists that are related, this causes the SharePoint List form to extract values from the two lists and populate the related fields.
My confusion is, where is the mapping of the fields occurring? For example how does the SharePoint list form know to populate the name field on the form with the name field from ListA?
Some of the fields have the exact same column names but others don't?
Example of List:
- List A (Contains User information)
- List B (Contains Car information)
- List form C (Contains insurance claim information)
Example of the URL:
