The material tax classification is missing in transaction WPUK in IS-Retai

Hi Friends,

I am trying to post "Sales As Per Receipts" with transaction WPUK in IS-Retail system.

After giving the necessary entries of article number, quantity, amount, when I save the entry, I am able to generate inbound IDOC number with stauts 51.

When I check the IDOC generated with transaction WPER, I get an error message in the IDOC generated as u201CThe material tax classification is missing in transaction I000000rOt 000001"

1) I maintained material tax classification for material master and customer master.

2) Maintained condition record supplying site receiving site tax class for material and tax classification customer and TAX code

Looking forward to your valuable inputs.

Thanks!

Regards,

BR
