About cash advance for employees

when i open new account in control accounts with name (cash advance for employees) , and try to make connection between this account and Payslip Deduction Items , it didnot done .

the account from (control accounts) didnot appear in payslip deduction items.
So how can i make this ?

You cannot post payslip deduction items to control accounts, because control accounts require subsidiary ledgers. (For example, Cash at bank is made up of bank accounts.) The payslip item must be allocated to an ordinary account, because it could be selected for any employee. See Set up payslip items | Manager.

I wanted to help @Medo with an alternative approach so I tried generating a custom report that would show the transactions (Loan advances and repayments with payslips) related to a particular staff from a balance sheet account meant to record advances/loans to staff and repayments. I couldn’t get the report to show the advances (payments) because a condition must be set to pick out the employee for the report and since employees do not show among the Payer/Payee list on the payment/receipt form (only customers and suppliers for now), the loans advanced transactions didn’t show on the report.

This leaves no choice but to create a general ledger account for every staff for the purpose of tracking staff loans and repayments if one wishes to see the loan balance of every staff without hustle or plan of easily generating loan balance statements for staff. Having Employee category among the Payer/Payee field on Payment or receipt forms would make it possible to generate such reports from the general ledger. I know the Inclusion of Employees in the Payer/Payee categories has been promised.

Have you tried entering the employees with a loan as customers (because they are a customer of the companies loan business).
Then list transactions in the loan interest account by customer.

Listing all of an entities transaction in Manager could be supported in the future by having a single contacts table / address book which contains a flag to determine if that contact should appear in the customer, supplier, employee, or expense claim payer lists.

The usual practice is to use payslips to manage the loan repayment.
