1) I have created a system module but while creating the line items created are in rows, but I want them in columns. how to proceed to this.
Click the pivot option highlighted in red in above image, in the pop drag and drop the linitem tab into columns and the List into Rows.
Hope this helps
Click on the Pivot button highlighted by @abhi1017
And then to save the module view. Go to View -> Save
tick this option and hit the save button
@kunal_311 The module view need to be saved as highlighted by @anirudh else you might see the existing view once the module is closed and revisited.
In the grid view of the module, there is an icon for pivot,
This enables you to pivot i.e change view of the dimensions, just drag line items from rows to columns as shown
Then you can save it by view, save as default
