How to link a value from a section into a detail and every time this value is changed in the detail the section value got updated as well?

Answer

The best to implement it is to create a business-process launching on editing the record in detail object in the field you have value in. Then you need to read this record in the object. You need to read 2 fields - the main record ID and the field with value you want ti update in main record. Then use the element "modify data" to simply modify the field with the value taken from detail record and specify ID=ID you have read in the Read data element (main record ID).
