How To Fix MW721 - In application WA individual messages are not processed

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 721

• Message text: In application WA individual messages are not processed

What causes this issue?

In the area of the allocation table, you need to distinguish
between individual messages and group messages
Individual messages - application GI
When saving the application data and for explicit requirements,
message determination (MESSAGING) is called for each material and
plant and an individual message is generated.
The processing of individual messages (for example, printing)
would have the result that the data (for example, printout) would be
transmitted for each material and plant. This is not intended; on the
contary, a list should contain data for several stock allocations.
Group messages - application W0
Individual messages are bundled and grouped together in group
messages. Processing (for example, printing) is only carried out for
group messages.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Start the bundling program (RWSNASTV) and then the processing
program for group messages (RWSNASTV).
