You need to remove the slash / from the employee ID and save (do these steps for all the employees). Then rerun Lampiran B. Please follow the steps below:
Restart your PC first, this is to ensure that any backend Excel process generated previously due to the Lampiran B is killed first.
Go to the Core module, Employment Details, Remove / in the Employee ID (If you would like to test for 1 staff, then query out only one staff to test)
Save
Then go to Payroll module, Reports, Government Form, Lampiran B.
