If I were you I would insist the vendor follow the standard. The ack should indicate the the proper systems and applications. I typically also want them to put in a unique Control-ID in the MSH.
Also the MSA segment should reflect the Control-ID that was sent in the message they are acknowledging (you did provide a unique Control-ID in the MSH you sent them didn’t you?).
With the above information, you can adequately trouble shoot questions about whether the GE app received any particular message.
Remember, after the vendor is done, YOU have to live with the results – and they already have your money.
