Hi,
I am saving the input in the Environment variable like below
SET Environment.Variables.Respmsg = InputRoot.MRM;
then, when I get the new values in the InputRoot, how can I "append" these new values into the original Environment.Variables.Respmsg in which I already have some values?
Please help
Thanks in advance |

Hi,
You can assign this in form of list as below:
Declare a counter i initialised to 1
start a While looop
SET Environment.Variables.Respmsg[i] = InputRoot.MRM[i];
increment counter (i = i +1
END WHILE
In this way all the values will be stored in Respmsg as a list one by one |

There is no shared state between two instances of a message flow, unless you specifically build it using a database or etc.
Every time any *Input node processes a new message, it creates an entirely new Environment tree.
This is Broker 101. Please get training. |

Yes if one message is processed then Environment variables will be cleared. there is no way that you can store it.
Sorry I thought you are asking about different records in same file. |

Although you could use a SHARED variable to store data between messages through the same flow...

Yes I am asking about different records in the same instance of flow.
I am in a loop and each time I am getting different values in InputRoot.MRM
I want to append this value to a environment value each time so finally when I come out of loop all the values are there in single env variable. |

This is a rather dubious bit of design; looping like this done carelessly (and sometimes done perfectly) can run an execution group out of memory.
There's been a number of threads in here about using aggregation or collector nodes to avoid such a loop. You may find these useful.

hi prasannanb,
U may did minor mistake in your loop.. Placing your code(specially a loop) here will help you better... |
