Item &: posting date OUTSIDE range of QS (&-&)

DEFINE &QS& = 'quantity schedule'

What causes this issue?

<DS:DE.BUDAT>Posting date</> of <DS:GLOS.goods receipt>goods receipt</>
NOT within the validity period of the
<DS:GLOS.release order>call-off</> &QS&.


&SYSTEM_RESPONSE& / &SYSTEM_MESSAGE&
If only one call-off &QS& line exists:
This message is controlled by Table T160M as a system message.
If the message type is 'W', you get an I-Message (information message).
If it is defined as an E-Message you get an error message (default is
'W'). If the posting date is not within the validity period of the
quantity schedule, the system updates the last &QS& line.
If more than one call-off &QS& line exists:
An error always appears (independent of the settings in T160M). The
system is normally able to update the LATEST quantity schedule line,
but in this case the &QS& is inconsistent, because the posting date
does not match the validity period of the call-off &QS&.

How to fix this error?

Enter a valid date in the validity period of the &QS& <ZH>or</> do not
select an item for this material movement with the given posting date
(use a different material movement, and use different posting dates for
updating GR (goods receipt) the call-off purchase order) <ZH>or</>
ignore this message (confirm update of last call-off schedule line).
If you ignore a warning, please avoid an extension of the call-off (new
schedule lines for call-off after update <GR qty> of last schedule
line). It is not possible to check this in quantity in schedule
maintenance.
If you use the "goods receipt" follow-on function in the display
purchase order, it is not possible to change the proposed posting date
(current date). If you do not ignore the message (I or E), then you
have to leave "display purchasing document", in this case, please use
the follow-on functionality within the "purchase order" menu or goods
receipt functionality in the "Inventory Management" menu.
