AXAPTA - Find a table fields label value

There are two ways to find a table field's label value:

If fields label value derived from directly fields extended data type:
 
    if (curext()=="krc" && this.RBOInventItemGroupId == "")
        ret = checkfailed(strfmt("'%1' field cannot be empty!..",
            new SysDictType(extendedTypeNum(RBORetailGroupId)).label()));
If there is a special label value dedicated at table level:

    if (curext()=="krc" && this.RBOInventItemGroupId == "")
        ret = checkfailed(strfmt("'%1' field cannot be empty!..",
            new SysDictField(tablenum(WholeSalesCampaignGroup),
fieldnum(WholeSalesCampaignGroup,RBOInventItemGroupId)).label()));
 

AXAPTA - Save query to a table field and restore than

I used Mirko Bonello's blog for this sample.

Create a container field at table. Mine is InventTableQuery:

void createAndSaveQueryInTable()
{
  QueryRun SysqueryRun;
  ;
  if (this.InventTableQuery)
      queryRun = new QueryRun(this.InventTableQuery);
  else
      queryRun = new QueryRun(queryStr('InventTable'));
   qrun.promptLoadLastUsedQuery(false);
   if (queryRun.prompt())
      this.InventTableQuery = queryRun.pack();
}

We used SysQueryRun instead for QueryRun and set qrun.promptLoasLastUsedQuery(false) for don't screw like me because of "Why I get same query values for every record?" question... :)

AXAPTA - Make a table field works cross-company

I learned this way from a forum . You have to just create a relation like up and care about extended data type of related fields. After that you won't need a custom lookup or supress validate method at forms. It works at AX 2009, I had no change to test with 2012.

AXAPTA control with code a field of datasource at form.

It's so easy. You have to use object array for that:    

SMAObjectGroup_ds.object(fieldnum(SMAServiceObjectGroup,
        Barebone)).enabled(SMAObjectGroup.ServiceItemType == B_ServiceItemType::Item);

AXAPTA TC Id field

This is just about turkish users:

There is an extended data type for TC id: IdentityNum_TR . But it's lenght incorrect (12). Should be 11.
