PA Internal Invoice- Rounding A/C issue

Hi,

For PA Internal AR Invoice when we create accountig in AR, a rounding account is generated. The accounting string getting generated is not correct and we want to correct it.

But we are clueless from where the system is deriving this rounding A/C string. Pls let us know how or from where the system derives this string?

Shouldn't it come from 'Intercompany Rounding Account' we define for the function 'Intercompany Invoice Accounts' as part of PA autoaccounting setups?

Pls share your inputs.

Thanks,

Mohit
