IDOC Mapping with field determination

Question

Hi All.
My requirement for this PI Mapping has the following. A root node (E1IDPU1) has a document name and document number. This also has a child node (E1EDP02) that can occur 5 times and in it a qualifier and belnr that occurs once in each instance.
We need to map either the qualifier from the child to the target field if the qualifier is "071" in any of the instances or if it doesn't then take the document number from the root. Problem i have is how do get this number if the process is done once, checking all the fields.
I have the mapping complete with an IF-THEN-ELSE clause that checks the constants for these but it will only evaluate the qualifier fine taking the belnr, my ELSE doesn't take the document number in the event qualifier does not exist.
Do help, it will be appreciated.
Darren.

Answer 1

Hi Darren,
I believe you are only passing one value to the target node. That may explain why you are having the error:
You can try using this mapping:
QUALF ----> replaceString --> removeContext --> sortByKey:numerical ascending -----------------------------------> \
Constant:071 --> /     /                                   /                                                        \
Constant:71000000 --> /                                   /                                                          \
BELNR ----> removeConext ------------------------------> /                                                            \
QUALF ----> replaceString --> removeContext --> sort:numerical ascending --> collapseContext --> equalsS: 71000000 --> ifThenElse --> TargetField
Constant:071 --> /     /                                                                                /
Constant:71000000 --> /                                                                                /
DOCNUMMR --------------------------------------------------------------------------------------------------------> /
The replaceString with constant 71000000 is there to ensure that 071 gets the highest number when the sorting function is called.
Hope this helps,
