Payroll scenario

Question

Dear Experts below is the scenario followed by the sample data from the clients place for a specific scenario to be modified.Please suggest whats the best solution
Pay the commission entitlement in two portions, the first payment (pre-payment) at the tender acceptance stage, with the second payment being made at the contract signing stage. u2022 Conditions of employment would state that the commission is not earned until such time as the contract is signed. u2022 We occasionally have projects that do not proceed to contract signing, and hence would reverse the pre-payment payment. u2022 The majority of our salespeople are paid a regular fortnightly retainer as well as commission. u2022 The commission component could be a % of the u2018tender acceptanceu2019 value, or a fixed dollar value. We may have to allow for both types. u2022 Would like to be able to enter some data and report on as well. Data would be; SAP Project number (i.e. J/001354), SAP project customer number, tender acceptance contract value. u2022 We would also like to enter both payments at the time of initial processing, with the u2018balanceu2019 payment being put on hold or block, (hence reducing the need for further entry. u2022 Reporting would consist of determining commission amounts outstanding (i.e. the balances that are on block & the project numbers) per salesperson, and what has been paid in a period say. u2022 Terminated employees can still get paid their u2018balancesu2019 as contract exchange, and reversals (of the pre-payment) made if they donu2019t. Below is the sample data for the above-Could you guide me how to match the above requirement.

12     Final Commission Payment Split     50%     Payroll Data     Variable per salesperson

14     Final Commission Payment Amount $1,300.25      Payroll Data     To be paid in first payrun after contract sign date
15     Contract signed date     22/12/2010     Contract Files/Payroll Data     Job Variable
Note:                    
     Items 9 through 15 would require new data fields in SAP (somewhere?)

Answer 1

If you create a Custom Infotype to store the Contract Information, use table T511K to store some constants (such as the 1% commission rate), and create a Custom Function to process your Custom Infotype, you will be required to create at least one or two PCRs to calculate the initial payment, and either the final payment or the recuperation of the initial payment.
I have never worked with the Australian Payroll Schema (if I remember correctly from your previous postings in the ERP HCM (HR) forum), but I would believe that you could place your Custom Function in the same sub-schema as functions P0014 and P0015.
