Hi Christain
Goto the view in component CRM_BT_TRANSINB which contains the table view ( for which you want to add a column )
*** First enhance the view by right clicking on the view
*** Now goto the context node class ( node of table view ) . Right click and enhance
*** Now you can right click on the view and add a field( attribute )
*** After creating right click on the field and Click on Add to Design Layer
*** Now go to the view configuration tab and Add the new attribute to the table view . so that new column will be displalyed
Let me know if any issue with this
Regards
