Hi,
I have an entity that is a copy of the salesorderline entity. and the main data source of the entity is that table salesline. I checked the column on the database and it has data.
I wanted to add INVENTTRANSID and since the column is already on the table, I just added it as a mapped column.

I also make sure the column is on the staging table of my entity.
I have deployed, re- generated the entity and export it to my BYOD.
And that column is empty.
What am I missing?
Thanks
