Hi,
Just a quick update on status here. Apologies for not having accepted any of the provided answers as the correct answer. Which is more my fault due to not providing the full and correct information. Having a meeting with customer today (last week was postponed by customer as they had to resolve other issues).
Once we've had the meeting to ascertain the correct issue, will either close this query, or update it as/if required.
Thank you all again for what you've provided so far.
Kind regards,
Bob K.
