This appears to be a customization issue, possibly caused by the following, but I'm not entirely sure.

Dynamics 365 Business Central: How to check if a record/table is temporary via AL

It would be best to have the developers debug it.

Thanks.

There is no customization for sales quote, order, invoice
1 field added for customer, and item master table, card, list/worksheet

5 new tables added which are not temporary
Later all custom tables are removed from customization and extension redeployed

Posting ended up with same error

Hello,
Posting Preview should simulate the entries that will be created without needing an actual posted Sales Invoice Header to already exist, so this error usually points to custom code/event subscribers/reporting logic that is trying to Get() the posted invoice header during preview, using the temporary/random posting number generated by the preview process. Since it works with one line but fails with multiple lines, I would first check extensions/customizations around sales posting, invoice posting buffer/grouping, posting preview events, dimensions, item charges, or any subscriber that reads Sales Invoice Header too early. Standard troubleshooting: test the same document in a clean sandbox with extensions disabled; if it works, debug the custom extension and guard the logic during Preview Posting or avoid reading posted invoice tables before the real post is completed.

Agreed with Yun Zhu, this sounds like a customization issue. You can create a copy of the environment and completely remove the extension and see if that fixes the posting preview error.

Does this happen with all invoices or just a specific one? When an invoice or order line is created it automatically validates the header and adds it as a field to the lines section. The only way this could be overridden is with a customization of some kind. Or if lines were created in an irregular way.

I'd try deleting any additional lines and try manually adding them back. Any new lines would include the header.

If it persists i'd recommend submitting a ticket with Microsoft or getting your partner to submit one on your behalf as they can look at system issues if there was a bug.

Best,

I have created a new sandbox environment for this and configured again, but this time no extension.

Same posting issue persist with Sales order or sales invoice preview posting

Next i have created an invoice with 0.01 amount single line item and posted without preview posting.
Now 1 dummy invoice is posted perfectly

After this, I have created 1 more invoice with multiple line items and tested preview posting and it works perfectly

Now I am not getting any posting or preview posting issue anymore

This just happened and seems a quick work around, still root cause is not clear

Hello,

If you are still not able to find root cause you can take a help from technical expert and debug in the sandbox to find an exact root cause.

Hope this answer helps you!

Hi,

the *** in the number is the giveaway — posting preview masks document numbers like that, so some code is trying to do a Get on the posted Sales Invoice Header during the preview, and in preview that record is never really there. Standard posting doesn't do this, which is why I'd bet on a customization or extension, usually a subscriber on one of the posting events that loops the lines and reads the posted header back. With one line it maybe never hits that path, with more lines it does.

Quick test, try the same preview in Cronus or a company without your extensions, if it works there you found it. Then check your subscribers and wrap the Get with an if-Get, or skip it when preview is active. I seen this a few times and it was always custom code, never base app. Does real posting go through fine, and do you have any add-ons touching sales posting?

Glad to help - follow up if anything is unclear.
