Auto Sales Order Shipment (SOS) is not being created

Hi ​@Hiralu 

Try deleting the Inventory ID from the first line (Back Order) on the SO screen => Click SAVE => Then add the deleted Inventory ID => Click SAVE => Click "CREATE SHIPMENT"

Best Regards,

NNT

​@Hiralu  this is a common error in Acumatica.

Reason: There is NO shipment plan record for that date
 

Missing or invalid shipment plan (INItemPlan) due to date mismatch or no re-planning.

Try once by changing the dates for the shipment and 

• Open SO line
• Change Qty (13 → 12 → 13)
• Save

I hope it will work!

thank you for the response , ​@nhatnghetinh I cant delete it has associated SO

​@nasir it doesnt let me change the qty , as total qty of 48 , 13 yet to ship and 35 has been already shipped 

​@Hiralu can you check any allocation linked to sales order, are you able to create the shipment from shipment screen by adding SO line?

​@Hiralu  have you tried by changing the shipment dates?

1. Shipping Rule on SO Line / Order

If the shipping rule is set to:

Back Order Allowed → system may defer shipment

Ship Complete → requires full allocation before creating shipment

Try setting it to Ship Complete = Cancel Remainder or Ship Separately depending on requirement.

2. Item Availability vs Allocatable Qty

Even though:

On Hand = 15

Available = 15

Qty Hard Available

Qty Available for Shipment (SO screen)

Sometimes:

Qty is available globally but not allocatable to SO due to settings.

 3. Warehouse / Location Mismatch

Ensure the SO line warehouse matches where stock exists

Check if:

Location is Sales Valid = true

Location allows picking/shipping

 4. Allocation / Reservation Settings

Check:

Require Allocation enabled on item / warehouse

If allocation is required but not done:

System may push to Back Order

 5. Item Settings (Critical)

Verify in Inventory Item:

Item Type (Stock / Non-Stock)

Require Shipment = true

Default Warehouse / Location

​@nasir yes I tried changing the date still same issue 

​@FarhanaM60 yes everything you listed was on the place correctly .

For now we have created new SO for that item line to generate auto SOS. 

Thank you all for trying to resolve this issue .
