HI Guys.

I need your help to map these item into cash & liquidity management report.

Operating Payments

Salary

Reimbursements

PF

Duties / Taxes

Advance Tax

Inter company - funding.

Client want to see the forecasting of al these things.

For example, the client make  salary payment or advance payment on a certain date but, they know retty well before that there will be cash outflow in future on certain date for Salary/ Advance tax.

How can we MAP all these into the reports.

Shall I make Planning Levels for each one. If so Shall I assign into the GL master with Planning Group. If so how I can generate the forecasting on the same.

Please provide your inputs

Thanks..
