Is there a specific reason why Calculated column will have Crawled property while it will not have Managed Property

Question

I have a calculated column (inside my sharepoint 2013 on-premises), which is based on other fields of type currency as follow:-

now i want to show this calculated field inside a content search web part. but i did not find any managed property representing this column. so i went to Central Admin >> Search service >> Search Schema >> Crawled Property. and i find the related item as follow:-

but there is not any managed property for this field. although i define the calculated column as site column... so can anyone advice on this issue?

Answer 1

AFAIK, in 2013 calculated columns were not automatically promoted. (This feature was removed in 2016 & SPO.) All you need to do, since you have central admin access, is create your own Managed Property for the field.
