Hi @Hassan Waseem ,
Thanks for using Microsoft Q&A !!
Unfortunately, AddMonths function similar like AddDay is currently not available in Azure Data Factory. You can have AddMonths functions available in DataFlow in Azure Data Factory. You can upvote an existing feedback over here so that other community members can also upvote and products team can plan to include this in future releases.
Also, please refer to this thread which talks about extracting the current month using substring and doing calculations on the month part. You could use a similar approach based on your date value in your case.
Thanks
Saurabh
