Hello,

Thanks for your response but the link does not work 

Hello @maryadu28 ,

i attached 2 documents to this message. Are you able to open those?

The topic i refferd to is called “Migration Job - Custom Field” and is posted by “Ntaylor”

Hope this helps.

Sorry, I'm a real beginner, but if I want to import an excel file into a custom empty table, I'll do excel migration? What procedure do I use?

I'm coming back to you about importing data from excel, so I've followed the documentation :

then I run the job , download the file, get a message saying that the 20 rows have been inserted, but when I consult the table in question I can't find the rows. 

Migration jobs usually have 2 steps. Import data into a temp table, Copy the data from the temp table into the IFSAPP table. Make sure you run both steps.

I followed the doc, yes you're right the data is inserted into a table but which one I don't know.
