Hello, I need to add validation for import to excel for example I am having data for 10 rows in that 4 or 5 columns are mandatory. In that 10 row, some mandatory data are missing . So I need to apply validation for that. Can someone please help me on this? Thanks in Advance, Divya
You should import the data into a non persistent entity. Then you can do your validation, if this succeeds store the data in an persistent entity. If it doesn't succeed provide the user with feedback so they can change it.
