Hi Vinit
Normally Travel Management Forms in portal are Adobe Forms which are both (Interactive & Non-Interactive). but to access these forms we need to Install ADS in the system & also make sure that Adobe life cycle designer is also Installed as this will only allow the forms to modify/check through T-code SFP. Normally we use two forms Travel request: FITP_REQUEST_FORM.
Travel Expenses: GLO_EXPENSE_FORM & PTRV_EXPENSES_FORM (use any)
Features to assign forms:
TRVFR - TRAVEL REQUEST FORM
TRVFE - TRAVEL EXPENSES FORM
Useful Tip: Copy the std forms to custom as you can change the logo's & Layout and assign them to the above features.
Hope this info will be helpful
Cheers
