+10Hello,
I created a migration for insert rows to product structure. But i need to exist check on migration rules or something like that. Because when i use twice same migration about my case, the rows created twice. So i dont want to do this.
I need a little bit help for avoid this situation. If the row values are exist than it should try to only modify instead of new.
Best regards.
+8You need to ensure you have all of the P and K attributes of the view mapped to your source data.
If you don't have the values in the source then use a function within your SOURCE or DEFAULT to perform a lookup for each value.
+24Make sure you migrate (define) both BOM_TYPE and BOM_TYPE_DB -
for example, BOM_TYPE_DB =M and BOM_TYPE = “Manufacturing”.
If you only migrate one of them, it interprets the other as null when it does the match, and therefore it decides to create a new record.
(This is only a problem when the _DB field is a key field)
+6Also you can define your own “P”s and “K”s under Method List Attribute… if you know your unique columns. Helps in auto generated key situations such as from sequences.
