The wildcard JSON-Path approach should work here as well, but I think you’ll need to use the Mapping Root feature of the Mapper to iterate over the outer array. So, in this case, you’d probably use the following as the Mapping Root in the Mapper:
$newPayload.PurchaseOrderERPRequest_V1.PurchaseOrder.item[*]
That tells the Mapper to apply the mappings in the table to all of the elements in the PurchaseOrder.item
array. Then, you would add a row to the mapping table that read the lineItemId
:
$lineItemId
And, then wrote it to every element of the AccountingCodingBlockAssignment
array, using this Target Path:
$AccountingCodingBlockDistribution.AccountingCodingBlockAssignment[*].lineItemId
thanks @tstack, archived this with below logic in mapper(did not used root path) :
Expression:
jsonPath($, “$PurchaseOrderERPRequest_V1.PurchaseOrder.Item[*].lineItemId”)[0]
Target path:
$PurchaseOrderERPRequest_V1.PurchaseOrder.Item[0].AccountingCodingBlockDistribution.AccountingCodingBlockAssignment[*].[“lineItemId”]
as expected, this is distributing the value evenly across any number of object under AccountingCodingBlockAssignment,
however problem here is if item field have 100 lineItemId, its impractical to pass index for each, also we are not sure how many lineItemId will be there in each request.
How this can be handled dynamically so that no need to pass hard-coded index ?
