Import Transactions Multi Item Sales

Thanks Braath
FA 2.3.24
Import Transactions 2.3.24-1

How do you deal with multi line invoices if reference is left blank?

I am thinking to still use reference from CSV file to detect a new document, store it on some memo (external reference) field on sales invoice, but always get a new sales invoice number for each new sales invoice being imported.
May be add a Boolean switch to Import Transactions to indicate whether to use invoice number from CSV or generate new.
What do you think?

I see what you have done:
- blank reference "" means get new number,
- non "+" reference means use this value as reference
- "+" reference means second, third, n-th lines of the same document
In other words - you only specify document number on the first line.

This way you can mix automatic numbers and given references in the same file, right?

Noticed your version has been merged in to FA24Extensions library. Tried multi line sales invoice import with blank references - came across couple of issues there:

1. $Refs->get_next($type) seems to return the same document number until transaction is committed;
2. block of code to get the number document number is too late (lines 274-277 in import_transactions.php), by the time process reaches it, document has already been created. Thinking it should be soon after line 202, after list function is called but before $reference is tested in line 208;
3. $_SESSION['Items']->write(0); (line 212 in import_transactions.php) eventually calls function add_sales_order(&$order), which tries to insert sales order, but sales_type and prep_amount variables are not set in $order object, so fails there as well

Question:
Is there a way to get several new document numbers in the middle of transaction before commit?

Thank you.
