Hi All,
I m using
chr_FieldType = 'dataType1';
blb_Msg =ASBITSTREAM(fieldref,int_Encoding, int_CCSId, chr_MsgSetID, chr_FieldType, chr_MsgFrmt)
to get MRM data as bitstream. But the problem is that if i provide chr_FieldType as one which doen't exist under "Messages" Structure in the .mxsd file (although it is present as "Types"), it doen't throws any exception rather just returns me a empty blob.
But i want the user to get Exception in this case.
Is there any way to find out Message Types in a message set, as i want to ensure that the chr_FieldType provided is among Message type provided. |

Hi jefflowrey,
I m using this line of code in a fucntion (to be used by large team).if the function throws an error at the Testing time and the messageSet would updated accordingly.
The problem is that what if the field didn't come in data, i mean the testing is caried out with this field missing,the blob would be empty in this case too....So i can't throw User defined exception only on the basis of Empty blob... |

So you have to check to see if the input field is not empty and the output blob is empty... AND THEN throw a user exception.
You don't need to do what you want to, which you can't do anyway.

Thanks Jeff,
But as per the coding standards this is not the Full-Proof way to handle this scenario. You should throw a Exception only in worst cases.
Guys do we have some way of getting the array of Messages defined in the MessageSet???

| No. The contents of the message set are not accessible from the message flow. |
