P4210 - Inventory commitment R42997(subsystem processing) is not splitting order detailed line

Hi,

We wanted to have detailed line split when partial quantity available at order entry. So we did below setups.

1. inventory availability and backorder allowed checks enabled in item, item branch, BP constants and customer master
2. Partial shipment and partial order shipment checks enabled in customer master
3. P4210 processing option#2 under process tab set to 3 (Subsystem Commitment R42997)
4. Add the batch version to P4210 processing option#13 Online/Subsystem Commitment (R42997) under versions tab

However, order detailed line is not getting split when partial quantity available at order entry. Both Qty shipped(SOQS) and Qty backordered (SOBK) reside in same line. We see that Inventory commitment program R42997 is active in subsystem process (Queue = QSUBSYS and Status=P) as per work submitted jobs. As per sales ledger, there is no entry with program id R42997.
