TAX code is not giving error for tax procedure TAXINN

[Private_Member_205888]

Hi Experts,

when i go to ME22n thru me23n and enter an invalid entry in tax code, my PO doesn't give error if tax procedure is TAXINN. when i create a PO for different tax procedure like TAXBD and enter an invalid entry in Tax code under the invoice tab, it gives error. But validation is not working for TAXINN in same system same client. i have checked the all configuration too. every thing is ok . Even this is working when i directly goto ME22N. but not working when i got via me23n. the validation working fine for all other Tocode like MIRO,MIGO etc.
