I am not able to hide the code line item here
due to this my import into OTH01 is coming wrong. I am getting an error everytime.
Go back to the grid view mode (not the blueprint view!) and configure your import view there.
You should be able to show/hide the necessary line items from there.
You will need to pivot your view. I recommend revisiting lesson 12.4 in the L1 Training for setting up your custom views for importing into other modules.
