On the Item Card page, under the Replenishment tab there is a field called ‘Replenishment System’. This can be changed whenever to any of the three values, and we used to be able to change this via API calls as well. There was an update sometime in the last year that changed something so that we could no longer update this field through the API, as it says that the field is read only, which is obviously not true. Does anyone know what could be causing this, or any potential work arounds (I’d rather avoid creating a whole custom page just to update this one field)? We really need to be able to update this via OData calls.
