MSONWL64 - Linux 64 Bit Memor Based Planner Errors Signal 11 Due To Profile MSO: Peg By-Product Supplies = No Being Ignored (Doc ID 1103706.1)

Oracle Advanced Supply Chain Planning - Version 12.0.4 to 12.0.4 [Release 12]
Information in this document applies to any platform.
MSONWL64 - Linux 64 Bit Memor Based Planner


On : 12.0.6 version, ECC Constrained planning in PROD - Users on ASCP Engine/UI CU6 patch 7518572:

ASCP - MSO: Peg By-product Supplies is set to NO and is being ignored - thus causing the failure

Non-standard WIP jobs contain negative quantities to represent the unused components of a tear down of configuration A to configuration B. These are considered as bi-products of ASCP but they are also components of an item in the rework BOM. Normally this item is already in stock and therefore explosion down to the bi-product component does not occur. However, when these items are still being manufactured the explosion to the bi-product component occurs, this causes a pegging loop problem for the high level scheduler, HLS, (there is no error for the unconstrained plan because it does not use the HLS scheduler).

Setting the profile MSO: Peg By-product Supplies to NO at the site level should prevent the error according to Note 957490.1. Also it should be noted that profile option MSO: Peg By-product Supplies = No. When this condition arises, the MSONWL64 module: Memory Based Planner 64-bit Linux errors with the following:

### Error: found loop between operations in HLSObjectDemand::recursivelyAddOperation
FROM operation : with sequence number 10 supply id 71093103 item id 42219 TO operation : with sequence number 90 supply id 70839378 item id 257232
Loop begins at :
supply id = 71093103 operation sequence number = 10 supply type = 5 item id = 42219 internal operation : id = 8504
operation : id = 8504 operation seq num = 10 supply id = 71093103 supply type = 5 item id = 42219
Program was terminated by signal 11


The issue can be reproduced at will with the following steps:

  1. Run ECC constrained plan with situation noted above and profiles set accordingly
  2. MBP 64 bit fails
