Huge InventSumLogTTS table

How to fix the performance issue due to the huge InventSumLogTTS table?
When you run Master Planning, the InventSumLogTTS table enables Master Scheduling to be updated based on the changes to transactions. After Master Scheduling runs, the records in the InventSumLogTTS table are deleted. When Master planning license is present and configuration turned on, the master planning execution should clean this log periodically. But when this is seldom used, the cleanup will be less frequent contributing to the growth of the table.
If you are running master planning on a regular basis then this table will get cleaned up.

Extended Query Range in Dynamics AX

Hi Friends, 

Many developers often stuck while they try to apply range to the Dynamics AX query to filter records based on some conditions. We will try to explore the query ranges in this article and will try to play with some examples to learn how we can apply query ranges using x++ to the Dynamics AX queries.
Let’s discussed different cases...

Query q;
QueryBuildDataSource qbd;
QueryBuildRange qbr;
q = new Query();
qbd = q.addDataSource(TableNum(CustTable));
qbr = qbd.addRange(FieldNum(CustTable, AccountNum));
qbr.value('4005, 4006');

The above x++ code will generate following SQL statement.

"SELECT * FROM CustTable WHERE ((AccountNum = N'4005' OR AccountNum = N'4006'))"

qbr.value(strFmt('((AccountNum == "%1")
(AccountNum == "%2"))',

The above x++ code will generate following SQL statement.

"SELECT * FROM CustTable WHERE ((((AccountNum == "4005") || (AccountNum == "4006"))))"

Let's say we want to apply "OR" range on a DIFFERENT fields
You can use the following
 x++ code to apply the OR range to the different fields

qbr = qbd.addRange(FieldNum(CustTable, DataAreaId));
qbr.value(strFmt('((%1 == "4000")
(%2 == "The Bulb"))',
fieldStr(CustTable, AccountNum),
fieldStr(CustTable, Name)));

The above code will generate following sql statement

"SELECT * FROM CustTable WHERE ((((AccountNum == "4000") || (Name == "The Axapta"))))"

Note: We have used DataAreaId field above to apply the range however, the actual range is on AccountName and AccountNum field. This means when you use range value expressions you can use any field to obtain range object and use it to insert your range in the query. Using DataAreaId field for this purpose is the best practice.
