hello,
You can update the material type setting (or create new one) which can be maintained on quantity basis but not valuated basis, so when GR is done refers to PO, the quantity of the material increases but does not increase the material value (instead it will increase the asset that defined in PO account assignment).
you can configure the material type with spro t-code menu:
Logistics General - Material Master - Basic Settings - Material Types - Define Attribute of Material Type
- select the material type used for the spareparts
- double click "quantity/value updating" on the menu tree on the left
- tick "quantity updating" field for each plant that will use the material
- do not tick "value updating" field (if ticked, we can't post to asset)
- save.
