SAP Error Message - Details

• Message type: E = Error

• Message number: 344

• Message text: Plant &: total & of delivery phases not same as & of plant

What causes this issue?

Plant &V1&; the quantity (here: &V2&) does not equal the sum of the
quantities of all schedule lines for plant &V1&.
This can have several reasons:
The sum of the percentages for the schedule lines does not equal 100.
The system rounded off the schedule line quantities.
The system uses the plant quantity to calculate the schedule line
quantities. It rounds off to a valid order unit to the number of
decimal places allowed for the order unit. Qantities are always rounded
off at schedule line level (even if order optimizing has not been set
for the rounding indicator) and guarantees that the follow-on documents
are generated with valid order quantities only.
