RPC Server Is Unavailable.

Yesterday I was working on Ax reports. And suddenly a message occured .
RPC server is unavailable when I was trying to open report even AOT.

Then I found "Print Spooler" service was stoped. So I started that service and My ax application was working fine.

By in group by is optional

public static void GroupBy(Args _args)
{
InventTable inventTable;
while select inventTable
group by itemGroupid
{
info(inventtTable.itemGroupId);
}
while select inventTable
group itemGroupId
{
info(inventTable.itemGroupId);
}

}

Here both will give same output. Really funny.

How to identify unused labels in application

We often creates labels in our development environment and we not use the labels.Following is a job to identify unused labels in application .

Here my label file is IFC

static void I4C_UnusedLabels(Args _args)
{
str 50 labelId;
int i;
int maxLabel = 2000;
xRefNames names;
XRefReferences ref;

str info = "LabelId#LabelStr\n"
;

while (i <= maxLabel) {
labelId = "@IFC" + int2str(i);
// The particular label file.
select recid from names
where names.Name == labelid
exists join ref
where names.RecId == ref.xRefNameRecId;

if (! names.RecId)
{
info += strfmt("%1#%2\n", labelId,

SysLabel::labelId2String(labelId));
}

i++;
}

}

How To Cache A object Globally in Ax

There are three way to cache objects.

A global cache is an instance of class - SysGlobalCache, which is nothing but a Map containing Maps with a Key. These Maps contain the actual value and a key.
In Ax, we have three Global Cache Classes

1.Infolog.globalCache()

2.Appl.globalCache()

3. ClassFactory.GlobalCache().

How to use:

static void GlobalCacheSetAndGet(Args _args)
{
SysGlobalCache globalCache;
class test;
;

globalCache = infolog.globalCache();

if (globalCache.isSet(classstr(test), 0))
{
test= globalCache.get(classstr(Test), 0);
return test;
}
else
{
test= new test();
globalCache.set(classstr(Test), 0, test);
return test;
}

}
