Posted on by Karthikeyan Venkates

I have three line items in my Sales Order.

For first line item have a Quantity as 10 Nos and Unit Price = 0.

For remaining two lines I have Quantity = 0 and Unit Price = 0.

Is it possible to post this as Sales Order ?

I tried, system allows us to post the Order. Why should system needs to allow this ? That has to check all line items whether Quantity or Amount has filled or not right ?

Can anyone please elaborate this .

Re: Posting of Sales Order with Zero Value

In Dynamics 365 Business Central, when you post a Sales Order, the system typically checks line totals, not necessarily each individual line for both quantity and unit price. Here’s what’s happening in your scenario:
Your Example
Line 1: Quantity = 10, Unit Price = 0 → Line Total = 0 × 10 = 0
Line 2 & 3: Quantity = 0, Unit Price = 0 → Line Total = 0
Business Central allows posting as long as the overall document total is valid, even if some or all lines are 0.
The system does not enforce that every line must have a non-zero quantity or unit price.
This is because there are valid business scenarios for zero-price or zero-quantity lines:
Free items or samples – you may want to ship items for free.
Placeholder lines – for services, optional items, or commitments.
Credit or adjustment lines – sometimes a line may have a zero value intentionally.

If you need stricter validation (e.g., no line can have quantity = 0 and unit price = 0), this can be enforced with:
===> Custom code or extension using AL code.
===> Pre- or post-validation via workflow or custom triggers.

Re: Posting of Sales Order with Zero Value

Hi,

According to me, it’s intentional:

Sometimes you might want to include items for reference, but not yet ship them.

Or, in real business cases, free samples or bonus items (Quantity > 0, Unit Price = 0) are valid.

Hence, the system doesn’t block the posting.

Do mark it as verified if this helps.

Re: Posting of Sales Order with Zero Value

There are several reasons the system allows posting zero-dollar orders, for example, to document warranty replacements or provide free samples and promotions without affecting revenue.

Likewise for zero quantity orders, there are several scenarios where it would be required. For this reason, the system lets you do it.

As long as the total amount is not negative, the transaction can proceed.

Re: Posting of Sales Order with Zero Value

Hello,

Business Central allows posting sales orders with zero price or zero quantity lines because it validates only that at least one line has a value to post.
Zero-value or zero-quantity lines are treated as non-posting informational lines, often used for free items, notes, or internal tracking.
The system ignores those lines during posting but keeps them for reference.

Regards,
Oussama

Re: Posting of Sales Order with Zero Value

Hi,

BC’s posting logic is intentionally flexible to support real-world scenarios like promotional items, free samples, or service placeholders. The system does not enforce a strict validation that all lines must have both quantity and value.

Here’s a solid option.

1. Posting Criteria

BC allows posting of a Sales Order as long as at least one line has a valid quantity and the document passes standard validations (e.g., customer, posting date, item availability).

Lines with zero quantity or zero unit price are permitted and will be included in the posted document unless filtered out.

2. Why This Is Allowed

Many businesses use zero-value lines for:

Free samples

Warranty replacements

Internal transfers

Placeholder lines for future fulfillment

The system supports these use cases without requiring workarounds.

3. Impact on Posting

Lines with zero quantity will not affect inventory or financials.

Lines with zero unit price will post with zero revenue but may still affect inventory if quantity is present.

These lines appear in the posted invoice unless filtered out via customization.

4. Optional Controls

If you want to restrict this behavior, you can:

Add custom validation in the OnBeforePostSalesOrder event

Use a page extension to warn users when posting zero-value lines

Customize the report layout to hide zero quantity lines, as supported in BC25.0

5. Related System Behavior

The Unit Cost field is not updated if the new cost is zero and the current cost is greater than zero

Some localizations or extensions may block zero-value postings, but base BC allows it by design

Re: Posting of Sales Order with Zero Value

Hello,

Business Central allows posting a Sales Order even if some lines have zero quantity and zero unit price because it supports flexible business scenarios like free items, informational lines, or planning entries.

The system does not enforce strict validation on each line, leaving it to users or custom logic to ensure data accuracy.

If stricter control is needed, it can be implemented through custom validations or workflows.

Re: Posting of Sales Order with Zero Value

Namaste @Karthikeyan Venkates

System allows posting of Sales order only if it has Quantity to be shipped , invoiced . It will show below error if there no quantity no value

In your case order got posted because there were other two lines which had value and quantity . And there were two lines which has no quantity no value

System has kept this provision because in case of bulk orders there are multiple shipments and in that case you can ship multiple set of lines different intervals . System allows blank quantity , zero amount only if there is something to post

If you feel this helped , please mark as "Verified"

Regards
