Symptoms

On : 12.2.4 version, Constrained planning in PROD:

Users are on 12.2.4 and have applied VCP Cum Patch 12.2.4.1 - 19549533 - using 64 bit Linux MBP with one off patch 25202143 using version MSONWL64.ppc 120.15.12020000.58.1220402.3

Users run EDD Constrained without Detailed Scheduling plan. They are seeing an issue where the plan output shows using a rank 2 sourcing rule for supply prior to using a rank 1 sourcing rule for supply. Example data:

MAS:DE1 Demand Org has sourcing rule with the following:
XFR From MAS:UEC rank 1 100% 2 day intransit - from earlier this has lead time = 73 days to make in this organization
XFR From MAS:HW3 rank 2 100% 3 day intransit - from earlier this has lead time = 13 days to make in this organization

Successor item relationships are setup as follows:

item = H00834-11-->H00834-13 (successor)
item = H00834-12-->H00834-13 (successor)

Dependent Demand coming from Org = MAS:DE1 for item = H00834-13 is being placed on rank 2 org = MAS:HW3 qty = 3970 on 11-AUG-2017 - this generates planned order totaling qty = 4140 (trans id = 92002192) in HW3 which has no current supply. The rank 1 org MAS:UEC also has no existing supplies
