Error while doing PGI

Hi all,

As we know that the accouts we set in VKOA will be used while generating the accounting document of billing document. we can see this account assignment in VF03 -> account determination analysis.

but my doubt is, while doing the PGI get the common error " the account ABC not defined in the Chart of account".

This error is for which account assignment in VKOA? how can i see this account assignment in sales order or Delivery?

Thanks,

Vidya
