TAXINJ to TAXINN, Note - 2161911

Hello Experts,

We are planning to implement GST, for that we are migrating our tax calculation procedure from TAXINJ to TAXINN.

As a part of the project now we are implementing following SAP Notes,

2167294

2153807

2056080

2161911

2014164

Now in Note no. 2161911 SAP suggesting that in standard function module 'FI_F4_MWSKZ' we will get Enhancement Point - 'KALSM_CHANGE' to implement.

But in our server I am not finding that Enhancement point in 'FI_F4_MWSKZ' Source Code.

Please suggest the best solution possible.

Thanks,

Sombhu
