R42997 UBE creates line 1.002 with TAX1=’N’

Hi,

The first line (1.000) shows the tax flag (TAX1) as ‘Y’.

 When ER42997 runs, it creates line 1.001 with TAX1=’Y’. This is correct

It also creates a backorder line of 1.999 and the TAX1=’N’.

why is the tax flag ‘N’?

Issue –

When ER42997 runs again, it creates line 1.002 with TAX1=’N’

We have a 2-line order, 1 has tax, and one does not

Please advise me on this.

Thanks,

Jaha
