Function Modlue

Hi All,

I want to make a function module for trip expance and time sheet data which can show the info like

1> for Trip EXPENSE:

Total amount

location

currency

date

project code

per nr

for trip info that i found in table catsdb that uses lot of structure but i want only these fields for some structure. can i create new structure by taking filed form these structure. In Fm my input is workitem id.

Similar is the case for time please suggest some standard that may contain the value for both requirement.

Then in both f i have to use 'SAP_WAPI_CREATE_WORKLIST', 'SAP_WAPI_OBJECTS_IN_WORKITEM' to create worklist and workitem.

2>for TIME:

total time

cost center/SO

attendance type

activity type

personell number

Thanks And Regards
