Problem in using fm CALCULATE_TAX_FROM_NET_AMOUNT correctly

[Former Member]

functional module CALCULATE_TAX_FROM_NET_AMOUNT has import parameter i_prsdt , which is a date for calculation of tax.

Although this field is not mandatory, but to get correct value I have to use it.

I am using this function in customized report for invoice open items using tcode FOYB.

I am unable to find 'Calc From Date' in SAP table with suitable key.

Although there exist a table VIBEPP and field is DBERVON.

It has key fields IMKEY , DTRANS, TTRANS, NTRANS.

I have value of IMKEY but don't know how to find value of   DTRANS, TTRANS and NTRANS.

Please guide.

This is recent appeared problem, because on implementation of new tax "Swacha Bharat Tax" in middle of month i.e 15/11/2015. You may be facing problem only in printing invoice document i.e in calculation of tax. Kindly wait for SAP note.
