Conditions during interface determination (urgent)

Hi all,

well i am using <b>conditions</b> during <b>Interface Determination</b> and according to the result of the condition a mapping program is triggered.

Now i am using <b>XPath.</b>

In my file i have a field called amount. The total of the amount field is stored in the trailer in a field called total.

Is there anyway that using XPath i can check if the sum of the amount field that r in the file is equal to the value in the total field?

a sample file would be as shown below ...

01xxxxxxxxxxxxxxxxxx -


02xxxxxxx10000xxxxxx ---

02xxxxxxx20000xxxxxx | body

02xxxxxxx10000xxxxxx ---

03xxx40000xxxxxxxxxx -



the sum of the amount field in the body (100002000010000) should be compared to that

in the trailer (40000) [the values in the amount field

will vary so does the total accordingly 😉 ]

can anybody suggect a solution ?? 😔

    Hi Shabarish,

    The only thing I can think off at the moment is to check the calculation in a BPM and set the "send context" property of the send step (so two send steps, one for equal, one for not equal) and check this value in the interface determination.

    • We did try using some functions and it gave surprising results...... eg. use compare and an error is thrown during interface determination in sxmb_moni, then we tried sum, and wow no error at all, but guess what the sum operation is not at all executed :-((

      anyway, thanx all for your inputs....

    1) Create an message interface for intermediate purposes.(which will have a field "flag" ).

    2) Design a mapping which performs your validations, (sum of body == trailers) (success/ failure) and assign the same to the intermediate Message interface ( set the flag).

    3) Now you can use this flag value and perform a interface determination.

    Hope this helps you.
