Create account string with ledger dimensions from code in Dynamics AX 2012
The information in this post is based on Dynamics AX 2012 R3. It may or may not be valid for other versions.
The way ledger dimensions work changed drastically with the release of Dynamics AX 2012. You have probably seen the dynamic account strings, in which main account numbers are merged with ledger dimensions into one string. This is handled automatically by the user interface, but as a programmer you may have to do the same from code.
The underlying data structures are rather complex, but fortunately the utility class AxdDimensionUtil can help you with this. Assuming you have a main account ‘0001’, a dimension called “Place” with a value of “Home”, and a dimension called “Purpose” with a value of “Expenses”, you can create a container like this:
dimensions = ['0001', '0001', 2, 'Place', 'Home', 'Purpose', 'Expenses'];
Notice how the account number is repeated; the first element is actually the display value, I just use the account number for both (I’m actually not entirely sure where the display value is used).
The third element in the container is the number of dimensions, two in this case. Then the dimensions with ID followed by value.
Finally, you can pass the container to the AxdDimensionUtil::getLedgerAccountId method, which will return a ledger dimension record ID you can use as reference on the records where you need it, for example on ledger journal transactions:
ledgerJournalTrans.LedgerDimension = AxdDimensionUtil::getLedgerAccountId(dimensions);
The actual display of the merged account string is still handled by the user interface, but this method can help you create the underlying data without getting too gritty with the details.
