物料主数据之Variable Units of Measure

在物料主数据的purchasing view中，有Variable Units of Measure这么一个字段。

SAP Help的解释是
 

Variable Units of Measure

 

In the material master record, you can specify that the material can be procured in a unit of measure that differs from the order unit.

If the material can be ordered in more than one unit of measure, enter

 

1

in the Variable order unit field.

让我们来做下实验。

如果此字段为空，采购单位为BAG，则在建立PO时，如果将单位改为PC，则系统会自动改回BAG并提示无法改为PC。

如果此字段设为1，建立PO时，将单位改为PC，则可以通过。
