Guys,
I stumbled upon a piece of code which uses InputRoot.BLOB.BLOB. The input message comes in CWF format. And I analysed the message and trace and the above code is actually resolving to InputBody.BLOB.BLOB.
Could some one please explain how this is being resolved?(I would have thought the InputRoot.BLOB.BLOB would start traversing from Properties header)
Thanks |

never mind i got it. I was confused with the 2nd BLOB. anyway it was a rookie mistake 
By the way, I have a Q regarding the CCSID stuffs. If I am working on ASCII character set, can i use any of the ASCII CCSID while casting InputRoot.BLOB.BLOB (ex : 437, 1208 etc)?
Also I have seen CCSID being set in almost every headers(Properties, MQMD, MQRFH2). So which one takes priority finally when it comes to Application data?
Thanks |

Use InputRoot.Properties.CodedCharSetId (or whatever the proper capitalization is).
When performing a CAST, the CCSID indicates what CCSID the data is in before the cast.

In case of the presence of additional headers use the CCSID of the header describing the message data.
Headers are typically chained, each describing the data following it.
So if you have MQMD->RFH2->Data the CCSID of the data part will be on the RFH2. Be carefull however not to confuse it with the CCSID of the property/value pairs of the RFH2.
Enjoy

In case of additional headers, I'm fairly positive InputRoot.Properties is set to the correct value for the InputBody.
