6013.Untitled1.png

this is leave setup form for "CL" we can take another leave "VL"   this is basic setup.

now iam going to first form 

6076.Untitled.png

i already applied a leave type is "CL" so as per my setup i can apply "VL" also

if apply second time in that drop down only "VL" should come because of in setup i have given "VL" for "CL"

for that drop down i have overwrite the lookup method in leave type code is shown bellow.

public void lookup()
{
LeaveReqHeader   _LeaveReqHeader;
LeaveReqLine _       _LeaveReqLine;
Query query= new Query();
QueryBuildDataSource qbds,qbds1;
QueryBuildRange qbr;
VacationTypeLineTBL      _VacationTypeLineTBL;
VacationType                   _VacationType;
_LeaveTypeMasters        _LeaveTypeMasters;

SysTableLookup sysTableLookup = SysTableLookup::newParameters(tableNum(VacationTypeLineTBL), this);


select _LeaveReqHeader;
select count(RecId) from _LeaveReqLine where _LeaveReqLine.LeaveReqId==_LeaveReqHeader.LeaveReqId;

if(_LeaveReqLine.RecId >= 1)
{

qbr = qbds1.addRange(fieldNum(VacationTypeLineTBL, LeaveTypeMasters));

while select _VacationType
{
select _VacationTypeLineTBL join _LeaveTypeMasters where _VacationTypeLineTBL._LeaveTypeMasters==_LeaveTypeMasters.RecId
&& _VacationTypeLineTBL.SerialNumber==_VacationType.SerialNumber;

qbr.value(int642str(_VacationTypeLineTBL.ITTI_LeaveTypeMasters));

sysTableLookup.addLookupField(fieldNum(_VacationTypeLineTBL, _LeaveTypeMasters),true);
sysTableLookup.addLookupField(fieldNum(_VacationTypeLineTBL, LeaveCodeDescription),true);


sysTableLookup.parmQuery(query);
sysTableLookup.performFormLookup();
}
}


}

if use this code in debugger i am getting correct value but drop is not coming its in disabled stage......

note:

1.VacationType    ,VacationTypeLineTBL     these two tables belongs to my leave setup form one is header and line 

2.LeaveReqHeader ,  LeaveReqLine these tow tables belongs two leave apply form tables 

this my code please review and help me out what is the mistake in that any other way to filter data 

thanks in advance.....

    Hi,

    I just changed your code and you need to perform lookup using joins instead of while-select loop. Please test the below code(if in case any syntax errors) as I don't have your objects and let me know if anything is missing.

    Refer following links:

    (lookup with joining two tables in ax2012)

    axaptaexplorer.blogspot.com/.../lookup-with-joinning-2-tables-in-ax-2012.html

    public void lookup()
{
    LeaveReqHeader   _LeaveReqHeader;
    LeaveReqLine _       _LeaveReqLine;
    Query query= new Query();
    QueryBuildDataSource qbds,qbds1;
    QueryBuildRange qbr;
    VacationTypeLineTBL      _VacationTypeLineTBL;
    VacationType                   _VacationType;
    _LeaveTypeMasters        _LeaveTypeMasters;
    SysTableLookup sysTableLookup = SysTableLookup::newParameters(tableNum(VacationTypeLineTBL), this);

    sysTableLookup.addLookupField(fieldNum(_VacationTypeLineTBL, _LeaveTypeMasters),true);
    sysTableLookup.addLookupField(fieldNum(_VacationTypeLineTBL, LeaveCodeDescription),true);    
        
    select count(RecId) from _LeaveReqLine 
    join Recid from _LeaveReqHeader
        where _LeaveReqLine.LeaveReqId==_LeaveReqHeader.LeaveReqId;
   
   if(_LeaveReqLine.RecId >= 1)
   {
        qbds = query.addDatasoure(tablenum(VacationTypeLineTBL));
    
        // Join _LeaveTypeMasters
        qbds1 = qbds.adddatasource(tablenum(_LeaveTypeMasters));
        qbds1.addlink(fieldnum(_VacationTypeLineTBL,_LeaveTypeMasters), fieldnum(LeaveTypeMasters,RecId)); 
        qbds1.addlink(fieldnum(_VacationTypeLineTBL,SerialNumber), fieldnum(LeaveTypeMasters,SerialNumber)); 
            qbds1.joinMode(joinMode::InnerJoin)); 
            // Add range 
            qbr = qbds.addRange(fieldNum(VacationTypeLineTBL, LeaveTypeMasters)); 
            qbr.value(int642str(_VacationTypeLineTBL.ITTI_LeaveTypeMasters)); 
            sysTableLookup.parmQuery(query); 
            sysTableLookup.performFormLookup(); 
       } 
    }
