Symptoms

12.1.3 in Production and Test
with VCP 12.1.3.5 Patch 12695590

PROBLEM
-------------
In our instance we have defined two plans 1. Manufacturing Plan & 2. Master Plan. We have migrated our data recently to our validation instance with the few items as MPP Planned and others with MRP Planning methods. But when we run the collection and the plans, few of the MRP planning items shows in both Manufacturing & Master plan where as it should show only in the MRP Plan. Please refer the screenshots document uploaded for additional details.

1. SQL check shows that all components of the item showing wrongly in MPP plan are MRP planned - so this is not a "sandwich" issue where MPP at lower level drives the results.
2. Customer also reports that they checked this same issue and could not find any sandwich setups.

So we found Loops in the snapshot log and are worked to resolve these loops
Then we still see the issue for some small number of items.

STEPS
--------
Run MPP plan, then run MRP plan.

EXPECTED BEHAVIOR
----------------------------
Not to see MRP planned items in the MPP plan

BUSINESS IMPACT
----------------------
cannot implement this planning strategy
