Incorrect Per-diems deductions


I have configured per-diems and dedcutions for a rollout. Now everyhting thing is working fine eexcept  a particualr scenario. E.g:

Start date : 1st Sept Start time : 10 am

End Date : 2nd Sept End time : 10 am

Deductions marked : 1st day :    Lunch and Dinner

                                   2nd Day : Breakfast

Now Deductions for Lunch and dinner are getting calculated properly but no dedcution is happening for Breakfast. Basically anything i mark on the second day, system is not calculating deductions.

Another Scenario :

Start date : 1st Sept Start time : 9 pm

End Date : 2nd Sept End time :  9 pm

Deductions marked : 1st day :    No Dedcution

                                   2nd Day : Breakfast, lunch and Dinner

Again, No deductions happen. System is not calcualting anything for the 2nd day at all. Am i missing something in customizing?




Hello Raj,

that can depend from the  country version (Molga, trip provision variant ?)

Please check first if you working with calendar-day caclulation or 24-Hour Intervalls (sm30 V_T702N_A: meal per diems calculationm: switch 17 and 19 )

You can identify this in the trip form too: On a multiday trip you can see in the trip form if the duration will be calculate every day from 00-24 o'clock or if an intervall from 09-09(next day) will be calculated.

If you have maintain a 24 hour intervall (switch 17 and 19 = '2') than it's possible that a breakfast might be not deducted - because system can not identify that this deduction belongs to the meal per diem evaluated intervall.

Therefore you have to activate the time-fields in the deduction screen. You can compare this with morei 03 austria/ or norway (20). Here the deductions will be combined wit the intervall .

Backend (e.g. PR05) Transaction FITVFELD

Travel Expense Manager


Time of meal  (Tech name) PTK04_BRFT_TIME

(setting Field is visible and ready for input)

with maintaining constants (sm30: V_T706_CONST)

B_DED, D_DED and L_DED you can set default values  (compare the setting with trip provision variant 20 B_DED has time: 05:00  as default/you can overwrite it in PR05)


Please check IMG activity:

Define Influence of Control Parameters: Deductions

only to exclude that deduction process should work only in case of a special trip type mandatory, and so on.

This should help you further
