Vendor debit at goods movement

Hello Experts,

I have a situation where the vendor should be directly debited for a particular goods movement.

The current process is split into two steps

Step 1.Goods movement using MvT 502, Accounting entries are

Inventory Cr

Gain/Loss Dr

Step 2. On save of above transaction, A Bapi is triggered to post and accounting doc, where the entries are

Gain/loss Cr

Vendor Dr

Now, the client wants that the Inventory Cr & Vendor Dr happens in one step. Is it possible to achieve the same via standard ? The To-Be process is as mentioned below

At goods movement using MvT 502, the accounting entries should be

Inventory Cr

Vendor Dr

Is the above possible ?

Thanks in advance for your valuable feedback

Regards
