Posted on by @rp@n 30

Dear All,

In calss we write generally Pack() and UnPack() methods.

In class decleration we declare the macro like :

#define.CurrentVersion(3).

#define.CurrentList

Can you please let me know what the numeric value 3 or whatever we put represent here?

Please give me more shed on this.

Thanks!

Arpan

    Hi,

    Macro currentVersion is for the version of the data and currentList is to store the values we want. The default value for #CurrentVersion is set to 1 by the compiler and it is the version stored in the cache by currentlist. If we add one field to the list, then we need to increase version by 1 (or with our choice but the version must differ numerically other than 1 like #define.currentVersion(3) and so on) as cache knows version 1 has 1 variable, 2 for 2 variables and so on.

    Please refer this link:

    axlearning.blogspot.com/.../get-last-form-values-in-dynamics-ax.html

    Hope this information helps you.

    Thanks Chaitanya,

    That means if i added 5 variables in CurrentList then currentVersion should be

    #define.CurrentVersion(5) or if 6 then it should be #define.CurrentVersion(6)

    Is't correct?

    Note : If it's mismatched means variables in currentList 6 and i put current version(2) then what will happened?

    Please give me more shed on this.

    Hi,

    It will not throw an error but in general, its recommended like that.
    Also, we can maintain different versions based on the list of values we want to store.
    You can check methods classDeclaration and unpack of class BOMROuteCopyJob and CustInterestCreate to see
    how different versions are maintained and retrieved based on the requirement.

    Thanks Sukrut and Chaitanya

    Finally one thing this concept is only for AX 2009 or AX 2012 also. Because in AX 2012 i didn't see.

    Please give me more shed on this.

    Hi,

    Along with AX2009, its applicable for other versions also. But in AX2012, BOF(Business Operation Framework) or SysOperation framework is introduced as a future replacement for RunBase and RunBaseBatch framework.

    Please refer following links:

    (From RunBase to SysOperation : Business Operation Framework)
