Help with mapping parents and child

, ,
1

I am working with SAP Business Connector. I am trying to do, what I think, should be a simple mapping.
I’ve tried to simplify this example. I basically have a SOURCE record list that looks like the following:

SOURCE (record list)

  • ORDERID (string)
  • TYPE (string)
  • LINE_ITEM (record list)
  • SKU (string)
  • DESC (string)

And a TARGET record list that is nearly identical except is does not have all of the same fields.

TARGET (record list)

  • ORDERID (string)
  • LINE_ITEM (record list)
  • SKU (string)

I just want to map the multiple records of SOURCE into multiple records in TARGET. I thought I would try mapping field by field. I can map SOURCE-ORDERID to TARGET-ORDERID fine. But when I attempt to map SOURCE-LINE_ITEM-SKU to TARGET-LINE_ITEM-SKU, I receive the following message.

[B2BCORE.0049.9019] More than one copy into the path with different common parent(s).

Any help would be appreciated.

Ryan

Loop over SOURCE to create TARGET. Within each SOURCE record, to loop over SOURCE/LINE_ITEM.

Thanks for your reply. I appreciate the help as I am a beginner outside the SAP world.

I had gone that route, but was having trouble appending using
appendToRecordList. I thought I only had to pass in the fromItem. I finally figured out that I had to also pass in the toList each time.

Thanks again for your help.
