Hello,
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.
You 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.
Make 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)
Also 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.
