NAV Classic 2009 R2 - Case statements

jonesks · 2017-08-14

Morning.

I am having to write case statements to pick out the country code and match it to the Country name. Tested it before I finished putting in the 80+ lines and It is just picking up the first case. It treats all customers as if it had GB. I inserted a test phraze in the first line - instead of blank I put "This is broken!" and when i ran the report it showed This is Broken on every address. Also I swapped the GB line for the SE line and ran it again to find out every address had Sweden on it.

I am obviously missing something but cannot see it. Can someone point me in the right direction?

Customer - OnAfterGetRecord()
CountryName :='Failure of address';

CASE "Country/Region Code" OF

("Country/Region Code"),'GB':CountryName :='';

("Country/Region Code"),'SE':CountryName :='SWEDEN';

("Country/Region Code"),'AE':CountryName :='United Arab Emirates';

("Country/Region Code"),'AR':CountryName :='Argentina';

ELSE

CountryName :='Not Working';
END

CASE "Country/Region Code" OF

'GB':CountryName :='';

'SE':CountryName :='SWEDEN';

'AE':CountryName :='United Arab Emirates';

'AR':CountryName :='Argentina';

ELSE

CountryName :='Not Working';
END;

You know that table 9 is used to retrieve country names according to country codes?

Try

VAR
  Country : Record 9;

...

IF Country.GET("Country/Region Code") THEN
  CountryName := Country.Name
ELSE
  CountryName := 'Failure of address';

Just to help you understand your first code:

CASE a_variable OF 
  something1a, something1b : do something 1
  something2a, something2b : do something 2
ELSE
 do somethng 3
END

is equivalent to

IF (a_variable = something1a) OR  (a_variable  = something1b) THEN do something 1
ELSE
IF (a_variable = something2a) OR (a_variable = something2b) THEN do something 2
ELSE
do something 3

What you have done is:

CASE a_variable OF
  a_variable, 'GB': do something 1
...

which logically translates to

IF (a_variable = a_variable) OR (a_variable = 'GB') THEN do something 1
ELSE
...

Can you see now why it was always picking the first line?

Is this C/AL? It likely won't even compile! Check the syntax.

jonesks · 2017-08-14

Yes it is C/AL and I am very new to it! It is compiling though. I know it must be the syntax but I cannot for the life of me work out what I have done wrong!

CASE "Country/Region Code" OF

'GB':CountryName :='';

'SE':CountryName :='SWEDEN';

'AE':CountryName :='United Arab Emirates';

'AR':CountryName :='Argentina';

ELSE

CountryName :='Not Working';
END;

Yes, just discovered that! When I said new to NAV - I mean two weeks! I realise what I did with the case statements now someone has pointed it out to me!
Now all I need to do is work out how to look up use table nine to give me the country name!
Thanks!
As Richard Branson said - if someone gives you a fantastic opportunity that you are not sure you can do, say yes and learn to do it later! (In my case thats on the job!)

jonesks · 2017-08-15

Ok - I know I can do this with about two lines of code - but I just cannot work it out! Any clues would be appreciated!
Thanks in advance!

Try

VAR
  Country : Record 9;

...

IF Country.GET("Country/Region Code") THEN
  CountryName := Country.Name
ELSE
  CountryName := 'Failure of address';

Not sure what you want there. You asked a question and you marked two replies as the answer. If there is something else you need help with, the best thing to do is create a new topic.

jonesks · 2017-08-17

Sorry for the confusion - The first answer works - it solves the problem I was having with the syntax I then realised that there must be an easy way to do it and the second answer is the easy way to do what I was wanting so both answers are very good and both work!

Yes - I had gone mentally blind! First time I have worked in C/AL and haven't done any coding for ten years. As soon as I saw AK's answer I kicked myself!
