Dear all,
I do not have the exact answer. I would like to provide some hint.
In action column, you may see edit or delete or both buttons. It is hard coded to determine what button is displayed in
CL_BTDOCFLO_HDRDOCFLOW_CN00
GET_OCA_T_TABLE
I do not know why there is no delete button on your webui. Per my understand, the delete button is always displayed no matter the document is in edit or display mode.
You may debug this method to find out why. Please remeber to check the view with F2 because you may have your own enhancement.
