How to update Business Central Inventory through API

(0) ShareShare
ReportReport
Posted on by kplatz 5

Hello, 

I am developing a Business Central Integration that requires creating Inventory adjustments. I understand creating Item Journal entries is the best way to do this, but is not possible through the APIs. There is a codeunit (1327) that can adjust Item Inventory, but I am struggling to find documentation on how to use it. I have added the codeunit row to Web Services, given it a name, and have an API endpoint to use. I am getting 415 Unsupported Media Type error in return when I supply any kind of body (json), but I can't find any documentation on what parameters are expected.

I have the same question (0)

    Why is it not possible to create item journal through API ?

    You can create a new codeunit with function to create and post the journal, and call that function using API. We have done this a few times without no issue.

    Depends on the procedure being used. Source code for the one I assume you might be trying is:

    procedure PostAdjustmentToItemLedger(Item: Record Item; NewInventory: Decimal) LastErrorText: Text

    I think the error is logical as a complete json representation of a rec value won’t be easy to replicate.

    Might be better creating your own codeunit based off this one. So instance if you swap the Item parameter to be a code[20]. Add logic to find the item record from your provided code value. After that the rest of the code is fine

    Thanks for the responses!

    To clarify, I was only trying to create Item Journal Lines, not post them. I was referencing the MSFT's API documentation, which only discussed the standard APIs. I did not realize that you could expose an existing page from BC Web Services, and POST new lines through the generated API. 

    Exposing the Item Journals Page got me what I needed. 

    Thanks!
