Review, research, and resolve issues in the MMMG job stream for all plants: Fin, Tup, TEx, Gua, Kru.
Wi can ignore these kind of alerts, and it not causing issue.

Will prepare clear documentation for what is the data flow for this 

Basic data flow is 

1. Plant engineer enter Master Data.
2. it will process through the 6090 interface to PMDR (PMDR is plant specific)
3. from PMDR data will move to the MMM( Hourly job will push data to MMM from PMDR.) -- This job will run from Morning 7 AM to evening 7PM.
4.. From Scheduled jobs MMM data will move to MES_BOM in LMAT -- This job is also hourly job.

Cause of the error message is.

for some materials it all attributes are not required. MMM job will write information this information is not required. so we can ignore these kind of messages.

And some message we should attention. if any time if we see MMM job failing alert mail it is very important to see.
