Populate dialogue processing box when raised work flow manually

Question

Dear all,
Wish to seek your expertise on this. When users raise work flow manually using t-code OAWD, they have to fill in the dialogue processing box. In the dialog box, user need to fill in company code, division of the company and country of the company.
As this is prone to error, it is suggested that to enter the company code only, then the division and country will be auto populate. To do this, a customized table will be maintained for the company code, division and country.
The given function module to bring out the above dialogue is Z_POPUP_GET_REQ_VALUES as shown in the coding below.
Do you know how modify the function module to import back the country and division from the customized table and populate the fields? Is there a need to use User Exit or Screen Exit for the dialogue processing box so that when user press "Enter" the company code and division will be filled in automatically? 
Thanks in advance for your help.

Hi Wanderer5 (is that your real name?)
I have no direct experience with starting workflows from OAWD, so I may be way off the mark...
So this is a workflow started by the creation of a stored document?  What type?  Can you tell if there are any normal events raised with the stored document? For example, if you are using invoice images, is the event BUS2081 CREATED raised? I ask because you could probably populate certain system fields from there. 
You may also be able to make use of user parameters for certain fields.
Hope this helps,
Sue
