Remote Call of WebDynpro applications with custom parameters in URL

Dear experts,

i have following scenario. There is an SAP-standard WebDynpro transaction which has to be called from the external system with some custom parameters in the URL.

Example:

This WebDynpro has to be called from outside with more than one Manufactoring Order and these values have to be put as a search criteria of the dialog.

Can you please give me some tips about:

- Is it generally possible?

- When yes, where I have to start?

- Is there maybe any tutorial for such a enhancment?

Thanks in advance and best regards.

Denis.
