Work Order Confirm Pick Slip - Not allowing to SPLIT Pick line for Lot controlled items

Summary:

We are encountering issues with partially picking and confirming a line for a Work Order component if it is lot-controlled. This process works correctly for non-lot-controlled items. For example, if a Work Order (WO) requires 400 units and there are two components each needing 400 units to complete the WO, the business often completes the WO partially in one day. They might complete 200 units and accordingly pick and consume 200 units for each component.

We have an integration from our Warehouse Management System (WMS) that uses the split line API to correctly split the pick line, confirm 200 units for each component, and leave the remaining 200 units open. However, this API fails to split the line for lot-controlled items. Additionally, from the front end, I can only split the non-lot-controlled item lines. For lot-controlled lines, if I delete the lot on the line, it allows the split.
