I have got a school's spatial data (point data) with capacity information in the attribute table. I have set up the Transformers to allocate the students to particular schools. But after allocating, I need to go back to the school's data for the next student. But after looping back, the data should show 1 less number in the capacity (because that seat got allocated to the student).

I am stuck here on how to go back and start the process again with reduced capacity.

Datasets I am using

Schools Feature Service

Master Spreadsheet with Students Data

Thank you
