使用X ++ AX 2012 R2在视图中循环浏览记录

Question

Loop through records in a View Ax 2012 R2( Need a job to achieve this)

I have a viewA where i have three fields Destination , Source, FieldX

I have a table where i have master list for Source This table contains S1, S2.....

In the view for each S1 i need to find the final Destination Value Example: Destination Source Type D1 S1 D2 D1 D2 No record found Explanation for above example: I took S1 from master list and placed in Source field in View. then I read Destination value for that Record which is D1. Now I placed D1 in the source field filter and i found a record with destination value D2. Now i took D2 and i placed it in the source field filter and i didnt find a record. i stop the loop here and i had to save D2 value.

For S1 , the final Destination value is D2.

Example 2:

Destination Source Type da s2 db da dc db dc No record found

For S2, the final Destination value is Dc.

I am not sure how i should loop in view for S1 to find the D2. I had to do this process one by one for all S1,s2.....Sn.

I tried few things using while/for or other loops with no luck. Can someone help me with a base code to acheive this?

Answer 1

How is the "final Destination Value" determined? What logic are you using to determine if a value is a "final Destination Value"? Is it complex logic or is it simply the largest value for that Source? Could you just join the view to the table and use a maxOf(Destination) on the view with a group by on the Source field?

Assuming it is not complex logic, something like this might be possible:

ViewA viewA;
Table table;

while select maxOf(Destination) from viewA
    group by viewA.Source
    join table
        where viewA.Source == table.Source

info(strFmt("%1", ViewA.Destination));
