The difference between CN00 and CN28

As far as SAP HR is aware, SAP provides two payroll schemas in China, one is CN00 and the other is CN28. The biggest difference is that one is to bring the results of tax revenue to the current month, and the other is to bring the tax base to the current month.

I now meet a client whose demand is that if the employee had a salary last month (there is payroll result), then bring the tax base to this month, if the employee's salary was not paid last month, then bring the result of the tax to this month:

So I looked at the difference between the two schemas and the results are as follows

First look at the differences in the SAP standard schema when dealing with the two tax models:

1. CN00: With tax results to the current month

CN28: With tax base to the current month

2. CN00 is used in the Cnnt

CN28 is used in the cnng

3. Cnnt is used in the Cntx

Cnng is used in the CNTG

4. The source code for CNTX is as follows:

000100 CNTXR calculation for tax partially paid by ER

The source code for CNTG is as follows:

000010 BLOCK BEG Process Individual Income tax

000020 PIT CN15 P67 noab Taxable foreign wage need spec exchange

000030 cngro re-convert Foreign Currency Amount

000130 ELSE Form Tax base diff and move ORT to RT

000140 COPY cntr Form diff for tax base

000150 ENDIF End of IF form tax base diff.

000160 BLOCK END Process Individual Income tax

5. The code for CNTR is as follows:

Line Func. Par1 Par2 Par3 PAR4 D Text

000010 BLOCK BEG Form diffrence and move ORT to RT

000020 Lpbeg RC Loop over old results

000030 imprt O Import old result (' x ' in ' y-1′)

000040 print NP ORT print ORT

000050 Lpend Endloop

000060 IF LPRC if:there is old result

000070 PIT CNL7 noab Form diff. To influx, tax base

000080 PORT CNL8 noab Get retro-relevant wage types

000090 PORT CNL5 noab Move old Data from ORT to IT

000100 ELSE No old results, calculate the

000110 PIT cnlb noab Form diff. To influx, tax base

000120 ENDIF End of If LPRC

000130 BLOCK END Form difference and move ORT to RT

The most important difference, by observation, is that in the schema of CNTG, it is judged whether the salary of the current salary cycle is calculated, if not, only the sum of the tax base and, if so, the tax base to be used to calculate the tax.

The final solution is as follows, the central idea is: whether in the current period, as long as the old salary results, calculate the tax base difference to the current period. As long as there is no, then directly in the period of tax, after the calculation of the current salary results added

1:copy CN28 to ZCN1

2: Change the cnng in ZCN1 to Znng

3:znng to change the CNTG in cnng to ZNTG
