Open PDF-File in WEBGUI ?

hi there,

i have business documents in PDF-format.

i am opening it in ABAP with

CALL METHOD cl_bds_document=>display

this works perfect for SAP WINGUI, acrobat reader is opened with the document.

BUT: i have to use my abap in SAP WEBGUI.

there i only get the info 'xxxxxx bytes downloaded' and NO acrobat reader is opened. it seems

that the document is only downloades somewhere.

any ideas ? i need to open the document 😔

reg, Martin
