I tried to open / assigning new material in transaction code O4NA, system throws an error as shown below
Materials in this tank: base UoM MT, UoM group API and conv.group 534B
Message no. OC805
Multiple materials assignments require the same base unit of measure,
and for oil materials, the same conversion group and unit of measure
group for materials that are assigned at the same time.
Only materials fulfilling the requirements are allowed for assignment.
A material which does not fulfill the requirement can be assigned to
this tank after the assignment of the other materials is complete. So if
the end date and time is open for the other materials, enter an end date
and time, and assign the new material with a start date and time which
is after or equal to the end date and time of the other materials.
Further information: i checked in MMBE for the stock balance, yes stock balance is there in restricted use and On order stock.
Kindly help to resolve this issue.
Thanks in advance.
