Hi Experts,

I created Material with wrong material type and valuation class in Production System. Transaction has been occurred with stock exist. I want to fix the material type and valuation class, then i try the method that i ever did in ECC. Its successful but sot sure if any huge impact, in ECC i did not faced any impact in my experience. In S4Hana Cloud, is there any hurt impact with the following tested steps? 

◆Steps Summary Done in Sandbox
