Generate number Sequence

Suppose we want create number sequence for Test field on form in General ledger module
Consideration: EDT-Test, Table-TestTable and Form- TestTable


Step1. Create new EDT with name Test
Step 2. Modify load module() method on NumberSeqModuleLedger class


{
datatype.parmDatatypeId(extendedTypeNum(Test));
datatype.parmReferenceHelp(literalStr("Test"));
datatype.parmWizardIsManual(NoYes::No);
datatype.parmWizardIsChangeDownAllowed(NoYes::No);
datatype.parmWizardIsChangeUpAllowed(NoYes::No);
datatype.parmWizardHighest(999);
datatype.parmSortField(30);
datatype.addParameterType(NumberSeqParameterType::DataArea, true, false);
this.create(datatype);
}


Step 3.Create a method on LedgerParameters Table


clientserverstatic NumberSequenceReference numRefTest()
{
return NumberSeqReference::findReference(extendedTypeNum(Test));
}


Step 4.Write and run following job


staticvoid NumberSeqLoadAll(Args _args)
{
NumberSeqApplicationModule::loadAll();


}




Step 5.Then run the wizard


Organization Administration -> CommonForms -> Numbersequences->Numbersequences-> Generate -> run the wizard.


Step 6.Now we have to check the number sequence is correctly working for that write a job:


staticvoid NumSeq(Args _args)
{
NumberSeq numberSeq;
Test num;
;
numberSeq = NumberSeq::newGetNum(ProjParameters:: numRefTest ());
num = numberSeq.num();
info(num);
}




Step 7.Now we want that Number Sequence in form level(Test Table):




Write below code in class declaration
publicclass FormRun extends ObjectRun
{
NumberSeqFormHandler numberSeqFormHandler;


}


Step 8.Write the NumberSeqFormHandler() in form methods node.


NumberSeqFormHandler numberSeqFormHandler()
{
if (!numberSeqFormHandler)
{
numberSeqFormHandler = NumberSeqFormHandler::newForm(LedgerParameters:: numRefTest ().NumberSequenceId,
element,
TestTable_DS,
fieldNum(TestTable, Test)
);
}
return numberSeqFormHandler;
}




Step 9.Write the Create(),Delete(),Write() , Validate Write(),Link Active()on the Data source methods node.
Create() Method
void create(boolean append = false,
boolean extern = false)
{
element.numberSeqFormHandler().formMethodDataSourceCreatePre();


super(append);


if (!extern)
{
element.numberSeqFormHandler().formMethodDataSourceCreate(true);
}
}


Delete() Method


publicvoid delete()
{
element.numberSeqFormHandler().formMethodDataSourceDelete();
super();
}


Write()Method


publicvoid write()
{
super();
element.numberSeqFormHandler().formMethodDataSourceWrite();
}






Validate Write() Method


publicboolean validateWrite()
{
boolean ret;
ret = super();
ret = element.numberSeqFormHandler().formMethodDataSourceValidateWrite(ret) && ret;
if (ret)
{
TestTable.validateWrite();
}
return ret;
}


Link Active() Method


publicvoid linkActive()
{
;
element.numberSeqFormHandler().formMethodDataSourceLinkActive();
super();
}
Step 10.Finally add Close() method on form
void close()
{
if (numberSeqFormHandler)
{
numberSeqFormHandler.formMethodClose();
}
super();
}
