view_document_from_table 

Use this method to display a document that is stored in an internal table in your ABAP program. To retrieve a document from the Business Document Service as an internal table, use the method get_with_table of class cl_bds_document_set .

You are strongly recommended to use the Business Document Service in conjunction with this method. Although it is possible to use it with standalone documents that you store yourself in the database, you then have to make sure that the parameters are correctly filled. If you use the BDS, the parameter values are provided automatically by the get_with_table method.
