Hi All,

I get this error while posting Vendor Invoice. Any idea why this will happen? The packing slip is posted by order quantity and vendor invoice is by product receipt quantity.

Thank you.

    Hi,

    Can you provide some more information? Do you have customizations in this area?

    Does the PO only contains items or also categories and/or misc. charges? Did you use a 'cash' payment method? Are all related number sequences setup correctly and do they issue a new number or does it use an already posted.number? What can be different compared to other invoices that can be posted without problems?

    Dear Sanme98,

    You should provide more details of your issue or error information to understand ur prob. As you are saying system should not give any error.

    Error: Voucher Doesn't have balance as per this date........ Check your posting profile.

    Error: Voucher Used Already : Check internal invoice voucher in Account Payable-> Parameter --> number sequence.

    Hi all,

    I am also getting the same error while try to posting the specific PO Invoice.
    We are using the manual Num sequence, and we are accepting duplicate in AP setup.

    During purchase invoice posting please check the no of line. Is it same as ordered?

    Some time it happens we try to invoice PO suddenly we close the screen and try to invoice this PO again so the PO pending invoice button gets enable in this case system keeps the previously selected invoice details in pending invoice button. If you try to invoice the PO system will give you two line previous one you need to delete and the current one you need to invoice.

    This may be case. try to delete the pending invoice lines if any.

    On LCS there is a mitigation proposal for a similar problem. You can try the next steps to solve this issue:

    Text below copied from LCS:

    1. Run a consistency check on Purchase Orders by going to System Administration > Periodic > Database > Consistency check.

    2. Select Purchase Order for the module and Fix Error in the Check\Fix field.

    If you are still unable to resolve the error:

    1. Go to File > Tools > Options > Development tab

    2. Unmark “Enable business operation in CIL”

    3. Go to the Server configuration Utility

    4. Unmark “Enable hot-swapping for assemblies for each development session”

    5. Try the consistency check again.

    I know it is old posted. But for my case the issue has been following:

    1. The PO line is procurement category only without itemId.

    2. PO was posted for Packing slip (goods receipt)

    3. The field Invoice remainder in inventory unit is 0 but invoice remainder in purchase unit is 1. Means the two qty not synced. 

    I run a script to sync both qty however haven't found the cause of it.
    it perhaps some bug as i see it is consistent all PO line with procurement category are having the issue but not with the PO line with itemID.

    But hopefully can help you or other user with same problem.
