Hi Guys,
I am parsing data i.e; packed decimal Comp-3 ... I have created a messge tree to read the data but while writing the data it is storing some junk values. Destination is a mainframe system, so i have used encoding 530. Just to show the actual data and the data my message flow is generating :
Actual Data : Y US 2
My Data : Y! US)2
If you notice there is an special character ) in the data which is actually suppose to be space.
The mainframe system is not able to read the message i am sending.
Can anyone help.. Thanks in advance |

What version of WMB? Running on what OS (and platform, as encoding is clearly an issue here). Is everything on Z/Linux or are you going "out and back"?
To repeat some good advice often given, have you taken a user trace to see what's actually happening when the output tree is built? How is your message set defined? Was it built by hand, or imported from a copybook? What is the source of the data, and how is that defined / encoded?
More information, more advice.

Thanks for the quick response.
WMB Version = 6.1 running on windows OS.
But the target system is z/OS. I have changed the CCSID and Encoding accordingly.
Message set is a CWF that is generated out of a copybook.
Surprisingly, i get the correct output when the values for the packed decimal is 1 or 0. For eg 110.00.
But when I give the values other than 1 and 0, i.e, from 2-9, it is giving junk value in the output.
Just curious to know whether packed decimal conversion is limited to only binary. |

No it's not.

Where? Broker, queue manager, input message or output message? These values should always reflect the values actually used in the message.

What's the picture of the clause(s) giving trouble? How is the field actually represented in the message set? What did the trace show?

I have changed the CCSID and Encoding at Broker level.
I can see the properties getting changed when i run the flow in debug mode.
Picture clause of the 2 COMP fields
05 ADTL-HC-PCT PIC S9(1)V9(2) COMP-3.
05 DISC-PCT PIC S9(3)V9(2) COMP-3.
In the message set I have given the type of the 2 fields as PACKED DECIMAL with length 2 and 3 respectively. |

Trace not debug. It has more detail.

I thought you said you generated the message set from a copybook? Why are you setting the values manually?
And why the change at broker level? What happens if the broker runs native and the message details are changed?

Describe output message properties and MQMD properties:
message/MQMD format
message/MQMD ccsid
message/MQMD encoding..

Input message is in a File so i am using a file protocol and not MQ. Here are the File properties :
MessageFormat CWF1
Encoding 530
CodedCharSetId 819

I am not changing the message set. I have imported it from the copybook.
I have developed a reverse flow just to decode the COMP-3 values and i am getting correct result. Even in RFHUTIL i can see the output file generated is correct.
Its just when that output file is fed to mainframe, it is giving some junk values.
I believe its the encoding issue or problem with ASCII to EBCDIC conversion because in windows system the value seems to be correct.
Can anybody tell me what is the encoding mechanism of z/OS system and what is the encoding code as I am using 530.
Thanks in advance. |

You should be using something like encoding 847 and ccsid 37 or 500... on the output
