Datasource precedence not enforced when CMDBTransformUtil used in import setIssue <!-- div.margin { padding: 10px 40px 40px 30px; } table.tocTable { border: 1px solid; border-color: #e0e0e0; background-color: #fff; } .title { color: #d1232b; font-weight: normal; font-size: 28px; } h1 { color: #d1232b; font-weight: normal; font-size: 21px; margin-bottom: 5px; border-bottom-width: 2px; border-bottom-style: solid; border-bottom-color: #cccccc; } h2 { color: #646464; font-weight: bold; font-size: 18px; } h3 { color: #000000; font-weight: bold; font-size: 16px; } h4 { color: #666666; font-weight: bold; font-size: 15px; } h5 { color: #000000; font-weight: bold; font-size: 13px; } h6 { color: #000000; font-weight: bold; font-size:14px; } ul, ol { margin-left: 0; list-style-position: outside; } --> Symptoms Yo have defined the data source precedence rules for source ADDM but they are not being evaluated when importing data from import sets.You are calling CMDBTransformUtil in the transform script. Release All releases Cause If you are using CMDBTransformUtil script include in your transform map, the code in the script include sets the datasource to "ImportSet"as opposed to ADDM or SCCM.IRE receives the payload with source as ImportSet and this will cause the rules defined with "ADDM" or "SCCM" to be skipped. Resolution 1. When creating data precedence rules, you should define the datasource as "ImportSet" so that the precedence rules are evaluated.
