First lets start off with having the definition of quantity conversion factor. Inorder to do so we need to define a data store object in which the conversion factors will be stored. we will go to transaction RSA1> Modeling > Infoobjects. Change the definition of infoobject 0MATERIAL. Go to the Business explorer tab and click on the new button right to the Units of Measure for Char. Box.
The system will now generate a datastore object in which the conversion factors will be stored. Determine in which infoarea the DSO will be defined and confirm. The DSO will be already activated.
Next, Activate the infoobject 0MATERIAL.
We can now take a look at the result: the definition of the Data store object UOM0MATE.
The next step is to load the data store object with the conversion factors.
