What's your actual scenario here?
Does it is possible to copy calculation fields from one table to another ? If so, do we have to establish the same set of relationships with the other table also.
Please advise me on this.
Regardless of the scenario, FileMaker Pro Advanced allows you to copy field definitions from one table to another.
Keep in mind, however, that in the case of fields, like calculations. FileMaker Pro Advanced will not auto-correct incorrect field and table references for you. In those cases, you will have to manually edit the calculation if you copy and paste it.
