Using the Cross company feature from the Business Connector.

 
19 Dec 2008 8:59 PM 

In Ax 2009 the new cross company feature was introduced. It allows the programmer to specify a container containing strings denoting company names to the crosscompany hint:
container c = ['dat', 'dmo'];
select crosscompany: c * from custtable where custtable.Name == "Jones";
That is all very well in X++, of course, but how do you handle it when accessing data through the business connector?
The first approach would be to do something like the following:
AxaptaRecord r = axapta.CreateAxaptaRecord("CustTable");
ax.ExecuteStmt("select crosscompany: ['dmo', 'dat'] * from %1 where %1.Name == 'Jones'", r);
However, that will not work: The argument to the crosscompany hint is not an expression of type container, it is a variable of type container. Hence you cannot provide arbitrary expressions, only variable references. This was done to make the implementation of the feature simpler.
The solution lies in the realization that the string that enters the ExecuteStmt is actually entered into a function that is compiled and executed at runtime. There are no limits to what can be expressed in this string, as long as it is legal X++ statements.
So, consider doing:
AxaptaRecord r = axapta.CreateAxaptaRecord("CustTable");
ax.ExecuteStmt("container c = ['dmo', 'dat']; select crosscompany: c * from %1 where %1.Name == 'Jones'", r);
which would actually work.

Mark All for Open Cust Trans and Open Vend Trans

We have situations where there are lots of open transactions that need to be settled against each other. This can be the case if auto settlement is turned off. One solution is to add a "Mark All" button to the custOpenTrans or vendOpenTrans forms. This button "checks" the mark checkbox on every line. The user can then uncheck several lines if needed and Update to settle the lines. The code below is an example of what we used on the open vendor transaction screen. The code is very similar on the AR side. One note: I used vendTable.AccountNum in the code below. That should be generalized to work with any buffer that is passed into the open trans form. void customMarkAll() { VendTransOpen localVendTransOpen; VendTrans localVendTrans; container conSum; int linesProcessed; ; //show wait cursor startLengthyOperation(); element.lock(); //remove all prior markings specOffsetVoucher.deleteSpe...
