I think this should be simple but I cannot find any solution - how to update a list item while keeping existing data?
So the new data will be added to the currently existing one in the particular filed on the list.
Hi Mateusz Kucharek,
If it is a workflow case.
1. Create another field in the list and while saving the item, in the workflow copy the current value to that temporary field.
2. And from the Next time onwards, get that temporary field value and append to current value and store it into your field.
Retrieving data ...
