Date & & not within range &-&

&CAUSE& Qty.schedule -> the second parameter (1-4) describes the
problem.
1. Scheduling period not within Qty.Schedule validity period or the
date of the scheduling line does not match the QS header data.
2. The contract validity period differs from the existing Qty.schedule.
3. The qty.schedule validity period either begins before or ends
after the validity period of the document (validity of the
contract), ("valid from" less than doc. "valid from" or "valid to"
greater than the document "valid to").
4. The new delivery date is outside the validity period of the assigned
qty.schedule, and the order (goods) has already been delivered or
received. It is not possible to change the delivery date if subsequent
documents (SD=delivery, MM=goods receipt) already exist.

System Response

While maintaining documents, if quantities have already been called,
you get an error message, otherwise you get a warning. Within the
Qty.Sched. you get an error message.

How to fix this error?

Take one of the following steps (depending on the number 1-4 of the
problem which comes up):
1. Enter a valid scheduling date or do not execute the function
'split line' or delete scheduling line.
2. Maintain/check the assigned Qty.schedule manually or semi-
automatically depending on the document type ("QS permitted"
indicator).
If the new "valid from" is before the qty.schedule: Check the first
scheduling period and insert a new scheduling period to keep the QS
consistent (avoid error <DS:NA.O1094>message O1094</>) for call-offs
with a delivery date.
If the new "valid from" is later than the QS: Check the first
scheduling period and delete the lines not already called off. If they
are already called off, it is not possible to delete the line and it is
not possible to change the "valid from" range to a later date.
If the new "valid to" is before the QS: Check the latest scheduling
lines and delete lines if possible (not already called off), otherwise
it is not possible to change the "valid to" to an earlier date.
If the new "valid to" is later than the QS: Check the last scheduling
period and insert a later sched.line if necessary (otherwise the last
scheduling period will contain a greater range of days).
3. Enter a valid range within the validity of the contract and use the
function "Restructure" if necessary after entering the valid range of
the QS.
4. Execute points 2 and 3 (delivery date change is not possible).
