How To Fix MW341 - & &: & not maintained. &

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 341

• Message text: & &: & not maintained. &

What causes this issue?

Not all the required data has been maintained.
The item category and the notification category determine which data
has to be entered, especially pertaining to sources of supply and
dates.
For the item category 'PO via DC", for example, you must maintain a
distribution center for every plant and an external vendor for every
distribution center. You must maintain delivery dates at plant level.

How to fix this error?

Enter the missing data.
You can enter some default data (e.g. delivery dates for plants) at
header level; the system copies the data to the items for the plants in
an item.
You can enter some data at item level (e.g. vendor, DC); the system
copies the data for the plants in the item.
Fast entry
You can enter DC data in a fast change screen by choosing "Edit".
Exceptions can also be maintained at plant level.
Certain data cannot be maintained directly in the allocation table
(such as the order unit). This data is adopted from the master data.
You must therefore add any missing master data and then create the
allocation table again.
