Dear SAP experts,
I changed some properties in material master by MM02, (in my case I changed the MRP group and Production sheduling)
but some days after that those properties return to initial value..
I checked the changes by MM04, There's a transaction when I changed the properties to the new value, but there was no record of transaction that returning the value. Last transaction recorded was CK40N, I checked with person authorized in costing transaction, and they said they didn't change a thing except estimating cost.
This happened many times,
Does somebody know why this thing happened and how to solve it?
I'm wishing for your help,
regards,
hachi
