Help with "iteration" in translation

[Tom Arrowsmith]

I am trying to write my first translation with the “iterate” function…. and need some help.

First, here’s an example of an HL7 message I want to translate:

Note that it has two OBR segments – and the values I wish to blank out are in the OBR-27.2 and the OBR-27.3 (“STAT” and “01”, respectively)

The translate I have written blanks out the appropriate values in the 1st instance of the OBR, but not the second.

I defined 2 iterate statements:

the first iterate details – ENGINE=group, basis=2(0).1(0), variable=%g1

then subordinate to the first iteration is the second –

The 2nd iterate details – ENGINE=field, basis=2(0).1(%g1).0(0).OBR.00221, variable=%f1

Then I have the staement –

@null @null -> {2(0).1(0).0(0).OBR.00221(%f1).[1] {2(0).1(0).0(0).OBR.00221(%f1).[2]

This all succeeds in correcting one of the OBR statements, but not both…

Any help would be appreciated!

Thanks!

In your copy statements, you are missing the %g1 variable in your destination fields.   Try it like this:

@null -> {2(0).1(%g1).0(0).OBR.00221(%f1).[1]

@null -> {2(0).1(%g1).0(0).OBR.00221(%f1).[2]

Hope this helps…

Yes… that makes sense.

Unfortunately, even after the addition of the group variable to the copy statement, I still don’t get it to work. Is the group defined correctly?

Thanks again for your help!

One question I have is do you have OBR.27 set up as a repeating field in your variant?  If not, then the field iteration is unnecessary.   Try taking that out.   If it still doesn’t work, then take you sample message and run it through the HL7 tester in the testing tool.   Turn the detail level up to about 3 or 4.  Then look at your grouping and it will give you an idea of how it is grouping and where your iterations should be.

Hope this helps…

Look at ‘Iterate Over OBR’, I had put some info regarding iteration that may help….in this
