Unable to Save Sales Orders for Model items

You are currently in R12.1.1 and planning to upgrade to R12.1.3.

The R12.1.3 instance has been set up and during Sales Order entry, you found that you are unable to create Sales Orders for model items.

The error being seen after entering the model item and saving is
"This Bill Explosion is already in progress in a different session. Please try again after some time."

Related note id "R12 Unable to Book an Order for a Model BOM_EXPLOSIONS OE_CONFIG_UTIL [ID 1302625.1]" in the support website. However this is a one-by-one datafix.
But the same error is occurring for other model items also. It is practically difficult to follow the solution provided in the note for every model item.
You have a large number of Operating units and huge amount of data.

Additionally, <Patch 15961704> was applied, but the problem is still there.

ERROR
-----------------------
This Bill Explosion is already in progress in a different session. Please try again after some time.
