Hi @Swati gupta
Currently we can pull only 50 fields in one Fetch task. So if we need more than 50 fields we need to create one more fetch task and have to Join.
Ex: lets consider you are using MDA Company Object
Fetch one Show fields should be: Company ID, the next 49 fields what ever you want to add
Fetch two Show fields should be: Company ID, another fields.
Merge: Fetch one with Fetch two use “Inner Join” as a Join Condition and choose all the fields from fetch one and choose all the fields(Except Company Id from Fetch two)
Hope this will resolve the issue for now.
Thanks.
