This post will help you if you have requirement to create a new record every time when a new record is created in another table.
Let me explain this with an example:
Assume that you have a master table 'Bank_Account' which contains a field 'AccountNumber'. Now the requirement is when a new Account Number is added (created) related to this Account Number a new table should be created as 'Transaction_####'. The name of the Transaction_#### would be dynamic.
If the Account Number is 1001 then Transaction_#### name should be Transaction_1001.
Follow the below steps:

If the Account Number is 1001 then Transaction_#### name should be Transaction_1001.
Follow the below steps:
- Create a table Bank_Account
- Add a field Account_Number (String)
- Set properties Mandatory : Yes , Allow Edit : No
- Make Account_Number as a Primary Key
- PK : Go to Index node > New Index
- Field AccountNumber has now become primary key.
- Override modified field method in table Bank_Account and write following code.
public void modifiedField(FieldId _fieldId)
{
SysDictTable sysdictTable;
Treenode treenode;// its a class
AOTTableFieldList fieldnode;
str Prefix,Acc,Tablename,prop;
int pos,Account_NumberID;
#AOT
#Properties
;
Account_NumberID = fieldNum(Bank_Account, Account_Number); // Getting Account_Number field ID
super(Account_NumberID);
this.insert();
Prefix = "Transaction_";
Acc = this.Account_Number;
TableName= Prefix + Acc;
//#Table path refer the \\Data Dictionary\\Tables and finding the path
treenode = treenode::findNode(#TablesPath);
//AOTadd method is to add table in tables//TableName is table name
treenode.AOTadd(Tablename);
treenode = treenode.AOTfindChild(TableName);
treenode.AOTcompile(1);
treenode.AOTsave();
treenode.AOTfindChild(TableName);
fieldnode = treenode.AOTfirstChild();
fieldnode.addString('AccountNum');
fieldnode = fieldnode.AOTfindChild('AccountNum');
prop = fieldnode.AOTgetProperties();
pos = findPropertyPos(prop,#PropertyExtendeddatatype); //find right place to put extended data type
pos = strFind(prop,'ARRAY',pos,strLen(prop));
pos = strFind(prop,'#',pos,strLen(prop));
fieldnode.AOTsetProperties(prop);
treenode.AOTcompile(1);
treenode.AOTsave();
treenode.AOTRestore(); //to load assigned extended data type properties
sysdictTable = sysdictTable::newTreeNode(treenode);
appl.dbSynchronize(sysdictTable.id());
}
{
SysDictTable sysdictTable;
Treenode treenode;// its a class
AOTTableFieldList fieldnode;
str Prefix,Acc,Tablename,prop;
int pos,Account_NumberID;
#AOT
#Properties
;
Account_NumberID = fieldNum(Bank_Account, Account_Number); // Getting Account_Number field ID
super(Account_NumberID);
this.insert();
Prefix = "Transaction_";
Acc = this.Account_Number;
TableName= Prefix + Acc;
//#Table path refer the \\Data Dictionary\\Tables and finding the path
treenode = treenode::findNode(#TablesPath);
//AOTadd method is to add table in tables//TableName is table name
treenode.AOTadd(Tablename);
treenode = treenode.AOTfindChild(TableName);
treenode.AOTcompile(1);
treenode.AOTsave();
treenode.AOTfindChild(TableName);
fieldnode = treenode.AOTfirstChild();
fieldnode.addString('AccountNum');
fieldnode = fieldnode.AOTfindChild('AccountNum');
prop = fieldnode.AOTgetProperties();
pos = findPropertyPos(prop,#PropertyExtendeddatatype); //find right place to put extended data type
pos = strFind(prop,'ARRAY',pos,strLen(prop));
pos = strFind(prop,'#',pos,strLen(prop));
fieldnode.AOTsetProperties(prop);
treenode.AOTcompile(1);
treenode.AOTsave();
treenode.AOTRestore(); //to load assigned extended data type properties
sysdictTable = sysdictTable::newTreeNode(treenode);
appl.dbSynchronize(sysdictTable.id());
}
- Override insert method of table Bank_Account and write following code
public void insert()
{
super();
info("NewTable " + "Transaction_" + this.Account_Number + " has been created");
}
