The invoice document 5105608835 contains the purchasing document 4151503102, and the item 00030. You cannot enter the invoice for this item, or you cannot cancel this invoice document. There can be several possible causes, for example:
– the PO item is blocked
– the PO item is flagged for deletion
– another colleague is currently processing the purchase order
– the purchase order has not yet been released
– the corresponding service entry sheet has been deleted
– for a held invoice against planned delivery costs: the vendor in the held invoice is not the same as the vendor in the condition in the purchase order, or the same as the vendor from the purchase order history entries. This is due to the fact that the vendor in the condition in the purchase order has been changed in the meantime. In this case, the held document cannot be processed further. You can use report Z_MRM_DELETE_PP from note 501905 to delete the document.
Check the purchase order.
