APP-PO-14078 ERROE ON PURCHASE ORDER DISTRUBUTION

[aasifbr]

HI,
I got error on Purchase Order's distribution form on <b>"PO Charge Account </b> field", only against <b>'EXPENSE'</b> type not on '<b>INVENTORY'</b> type. The 1st error is shown as <b> Values have not been entered for one or more required segments</b> and then give 2nd error i.e. <b><b>APP-PO-14078</b> A PO Accrual account is mandatory and could not be determined. Either select a different PO charge account or review your account generator setup.</b> and 3rd error is i.e.<b> APP-PO-14040: Please enter a valid charge account</b>, although i have given all accounts

Please give me needful solution.

<b>Regards,

Asif</b>
