Account number for transaction type Service tax does not exist.

Hi Friends,

While processing project invoice system giving the error as --Account number for transaction type Service tax does not exist.

Please note--

1). I am able to post Free text invoice with service tax but not able to post Project invoice with service tax code, if i remove service tax code then system will allow to post Project invoice.

2). This setup is for India tax.

3). I have checked the service tax GL A/c setup -- posting type is service tax only.

4). If setup is wrong system will not allow to post even free text invoice also i think.

5). Using Ax 2012 R3-CU11.

please suggest.
