SAPUI5 Display purchase order line items based on matnr show menge in correct unit

Hi Experts,

I'm having trouble finding the right function module to display the Unrestricted-Use Stock ammount ( in the correct unit of measure )per purchase order line items based on matnr in a sapui5 application.

As you can see

You instantly see a difference in unit, above it is ST( which is a unconverted value as you can see below). This I found I could do with fm CONVERSION_EXIT_CUNIT_OUTPUT. But the conversion that happens to show the 5 in stead of the 5.000 value I cannot find. Can you experts help me?

I get this data from a view I created and i expose this data via an odata service.

Kind regards,

Ian Desmet
