Hi,
error message says that maximum amount is missing in T706V.
T706V has two views: one is per diem view in IMG, one is max amount view in IMG. per diem view filters on entries type P, max amount view filters on entries type H.
You will find both types of entries in SE16N for T706V.
To disable, check expert view V_T702_N_A. Docu of switches available in IMG help. Line "meal per diems", position 8 - 11 or something.
Also check IMG V_702V_B - should be empty.
cheers, Michael.
