unit of measures conversion issue - inforecord in PO

We encountered unit oof measure issue when creating a PO.

We found out the error follows a certain pattern :

a) POs created for info record where all the condition types are maintained in the same unit of measure ( base or ordering nit of measure ) have no issue with unit of measure conversion in PO.

Assumptions:

-Material master isaintained in base and other unit of measures

-unit of measureconversio is maintained in the info record

b) POs created for info record where all the condition types are maintained in different unit of measures ( base and ordering nit of measure ) have issue with unit of measure conversion in PO .

Assumptions:

-Material master isaintained in base and other unit of measures

-unit of measureconversio is maintained in the info record

Is jemand out there who encounters the type issue?

I will be glad to receive your comments regarding that issue.

Thank you,

Emmanuel
