O4NA - Open / assignment of new material


Hi Guys,

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 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.

System Response

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.
