I am having this issue with dataloader. I am doing an insert and I get an error:
id value of incorrect type: ABCD
Where ABCD is my value. I have 2 custom objects and CustomObject2. CustomObject2 has a field which is a lookup relationship to CustomObject1. I have looked online and I know I need to pass the ID to this lookup field in my csv file. However since it is an insert I do not have the ID. How would I insert my value ("ABC") in this lookup field?
