You're not getting an error because you specified allowmissing=yes, and it allowed everything to be missing. I recommend you (and everyone) drop allowmissing=yes in favour of the countprefix option. With countprefix you have to do more coding to add the counter subfields to your data structure, but you have much more control over what you want to allow to be missing.

Say you know that CasePack might not be present in the XML, then you'd code a counter subfield, starting with a prefix, say "num" and ending with CasePack.
D PoDetailType ds
D LineNumber 6
...
D SlsCnfNum 15
D SlsCnfDate 6
D CasePack 9
D AirFrtFlg 1
D AirFrtRsp 10
DAssistChargeReq 1
D AsstCharge 15
* Countprefix subfields for optional XML data
D numCasePack 10i 0

Then instead of allowmissing=yes, you'd code countprefix=num and then in your processing, you'd check whether numCasePack had a count of 0 or 1 to see if CasePack had been in the XML for that element. Just add a num subfield for anything that's optional in the XML, and then if something is missing that's not optional, you'll get an error from XML-INTO.

Or, add a counter subfield for every subfield, and do your own post-XML-INTO validation on which information you want to allow to be missing.

For folks still on v5r4 that don't have the countprefix option, I recommend leaving out allowmissing=yes while first developing the XML-INTO code, and just make sure your sample XML doesn't have anything missing (if you need arrays, keep the number of elements in the RPG and XML small, say 2, so you don't need to provide too much XML data). Then when it's working in general, you can put the dimensions back up where they should be, and add the allowmissing=yes back in.
