Hi all,
I need to create new charge lines in a freight order by means of a Z-program. I have tried to use method DO_ACTION of service manager for /SCMTMS/IF_TOR_C=>SC_BO_KEY using /SCMTMS/IF_TCC_TRNSP_CHRG_C=>SC_ACTION-CHARGEITEM-ADD_NEW_CHRG_EL_LINE, but failed so far. Actually the line is created but the amount is just ignored and remains blank.
I have then tried to modify the created line to kind of "add" the amount with method MODIFY but again it would not work. I debugged method /BOBF/IF_FRW_DETERMINATION~EXECUTE of class /SCMTMS/CL_TCC_CHRG_EL_D_AM and the strange thing is that method MODIFY_AMOUNT is called only for creation. I tried using both change modes but it does help. Also, these methods are private and called for determinations so I'm not sure I could manage to call them directly.
I have found an old thread (How do I create new Item charge element under c... | SCN) where people manage to do exaclty the contrary but still not working (and lacking some explanations about how to get all the keys). Here's the coding I used in case someone's done that already:

create data lr_element.

append ls_modify to lt_modify.
lo_srv_mgr_tor->modify(
exporting
it_modification = lt_modify
importing
eo_change = lo_change

And then save changes with the transaction manager (not posting coding).
Thanks to anyone who's got an idea
