Message type: E = Error
Message class: M3 - Material Master
Message number: 644
Message text: No matching alternative BOM exists
Either the combination of alternative BOM and BOM usage entered by you
does not exist for the material, or the period of validity and/or lot
size range of the production version is not fully contained in the
BOM's period of validity/lot size range.
The system checks the validity of the combination you have entered
using quantity structure determination "++++" from Costing. This
quantity structure determination must be configured so as to meet the
maximum check requirements in material master record maintenance.
Check the configuration in Customizing.
If you are not authorized to do so, contact your systems administrator.

SAP messages fall into 3 different categories: Error messages
(message type = E), Warnings (W) or Informational (I) messages.
An error message will prevent you from continuing your work - it is a hard stop and you need to fix the error before you can proceed. A warning message will stop your work, however, you can then bypass the warning by pressing the Enter key on your keyboard. That said, it is still good practice to investigate the cause of the warning message and address it. An information message will not stop your work and is truly just for informational purposes.
