How to update delivery quantity via BAPI?
<p>In my business scenario the WMS system post GI of deliveries and send the info to SAP.</p>

<ul>
<li>If WMS post GI for the entire quantity ==> no problem</li>
<li>If WMS post GI for quantity &lt; delivery quantity ==> problem.</li>
<li>I should update the delivery quantity (LIPS-LFIMG) and then post the GI.</li>
<li>I tried with WS_DELIVERY_UPDATE and with BAPI_OUTB_DELIVERY_CHANGE without success.</li>
</ul>

<p>Have you ever faced this case?</p>
