Hi All today i am covering a small topic which is Maps in AOT
Maps are nothing just an element/object the makes possible to link/associate map fields with fields(same type with different names) in different tables like, I have create a MAP with field (AccountNum) and Same field exist in CustTable and also in VendTable,so I can associate field in CustTable and in VendTable with Maps, so basically Maps enables to access the fields with different name in different tables.
I have created a Map by navigating to AOT>Data Dictionary>Maps and right click and new and gave it name ‘MapTest’
I have created 4 fields in under Fields node in Map (drag and drop from EDT)
Now the next thing I need to do is to associate the fields in map with the fields in different tables, let say I am taking two tables (CustTable and VendTable).
Notice that above, four fields that I have created in Maps also exist in CustTable as well as VendTable with different names.
To associate fields, go to Mapping node, right click it and click New mapping, and enter the table that you want to associate in Mapping Table field. Like
And the associate fields with fields in MAP
Now I have created a method called printInfo under method node in Maps, which print the value of the map field AccNumber.
public void printInfo()
info(strFmt(“Map : AccountNum :%1”,this.AccNumber));
Similiarly I have create same methods under method nodes of CustTable and VendTable which are printing their respective AccountNumber fields
Now finally I have created a job see below I am not describing every line as I have added comments above the line.
When I run this job see what happens
