How To Fix MW371 - & &: latest generation date (&) is not before delivery date (&)

SAP Error Message - Details

• Message type: E = Error

• Message class: MW - Messages IS-R / Allocation Tables

• Message number: 371

• Message text: & &: latest generation date (&) is not before delivery date (&)

What causes this issue?

The system compares the delivery date with the latest possible
generation date, i.e. with the date by which a follow-on document must
be created for the goods receipt to arrive on time.
The latest generation date is contained on the details screen for the
plant or distribution center.
The generation date can either be:
calculated automatically by the system
(if the item category is configured to allow this)
entered manually in the header screen of the allocation table
The system uses the latest generation date in generating follow-on
documents to select entries from the worklist (especially when
generation is run in background mode).
If the latest possible generation date is not before the delivery date,
follow-on documents may possibly be generated too late and as a result
the goods receipt would not arrive on time.
If more than one delivery date exists for a plant, the message is
issued only once per plant. The message then refers to the first
delivery date for which the error occurred.

System Response

If the delivery date is before the latest generation date, the dates
cannot be met. The allocation table item involved cannot be released
for follow-on document generation.
If the delivery date is the same as the latest generation date, the
allocation table item is released for follow-on document generation.

How to fix this error?

Check the dates and if the follow-on documents can be generated on
time. You may have to change the dates or start the generation program
again manually.
