Hi everyone,
I am working on my project where I am supposed to send the ISO message to third party using TCP/IP protocol.
The Iso message is 0800822000000000000004000001000000000301225113000000061MCP02, but the message I am supposed to send the third party as follows 03FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFDCDFF444
0F080082200000000000000400000100000000030122511300000006143702000
where 003F is the length and the remaining message is the unapacked Hex. I am successfully creating a message as 0800822000000000000004000001000000000301225113000000061MCP02, but not sure how to convert it to unpacked hex in esql.
Can please somebody suggest me how to do it. its really urgent.
Thanks in advance! |

What version of WMB/IIB?
Why are you trying to do this in ESQL rather than MRM/DFDL?

| I am building ISO the message in WTX map. We are using WMB 8. the response from the map looks like 0800822000000000000004000001000000000301225113000000061MCP02. Now I have to add the length of the message and convert it to unpacked hex in esql before sending it. |

If you're using WTX (which is a fairly comprehensive data transformation engine) I again ask why you're trying to do this in ESQL

WMB v7 was not able to read and write ISO8583 because the MRM parser could not handle the bitmaps.
WMB v8 is capable of reading and writing ISO8583 messages ( using DFDL ) without the need to call out to WTX. See https://github.com/DFDLSchemas/ISO8583
The data that you are starting with is a different length from the 'unpacked hex' that you claim you want to output. I cannot work out what the conversion logic should be. Do you know? Are you sure that the '03F' at the start is a length?
Are the 0xFFs representing the ISO8583 bitmap? If so, then you need to look at the ISO8583 sample that comes with WMB v8 ( it shows how to set the bitmap using ESQL ). If you decide to use this technique then you need to be using WMB/DFDL for writing the ISO8583 message, not WTX.

Hi,
I could do the needed conversion using CCSID 37.
Thanks everyone for your help! |
