Could be related to the bug that was fixed with OSS note 2346126 - Field XBLNR saved incorrectly
How about if you revoke and delete the SES, then create new SES? Can the invoice be posted then?
Hi Madhavi,
Please start checking with your MIRO layout you must have select "Invoice" as transaction, then select Item Type as Goods/Service Items, also check the material document created against your Service entry sheet!
If still not get resolved than please share the screen shot of your issue right from the beginning like PO>SES>Material Doc>Error Message.
Thanks,
Ankur
FYI, another possibilities that introduced and fixed by OSS note 2093640 - M8038 - PO item does not allow invoice receipt.
