Hi Dinesh,

So what you want is, if the reason code parameter is true, and in the from it's empty then throw an error when postong OR if original invoice parameter is true and payment method is empty then also throw an error?

Which means you need sth like this on maybe the post clicked method (ignore the syntax just showing you the idea as I'm on my mobile)

If(parameterReason == noyes::yes && this.Reason == '')

{

Throw error('error');

}

Same thing for the other field.

So can you show us your code in order to know what u did wrong?

Thanks,

Layan Jweihan

Hi Dinesh,

What is the error you are getting?

Looking at it quickly, i can see a major issue, which is you didn't select the projParameter and you are using it directly, so that will generate an error.

You need to say sth like this:

ProjParameters projParameters= ProjParameters::find();

Also you said you want to check if they are empty when the parameter is yes, but i can see you are not doing that, you are rather making them mandatory..what is the exact requirement?

Thanks,

Layan Jweihan

Hi @Dineshkarlekar,

What is the error that you got?

I see three errors on your code:

1- You don't select projParameters buffer.

2- You called the table buffer to set the formdatasource field mandatory which is wrong.
3- You use the same parameter field to mandatory of Method of payment and ReasonCode

Try this code and tell me the result:

Note I named the fields based on what you mentioned but you should use the correct names.

[ExtensionOf(formControlstr(ProjInvoiceProposalDetail,ProjFormLetter_Invoice))] final class DTInvoicepropCreditnt_Extension { public void clicked() { FormButtonControl formButtonControl = any2Object(this) as FormButtonControl; FormDataSource formDatasource = formButtonControl.formRun().dataSource(tableStr(ProjProposalJour)); ProjProposalJour projProposalJourds = formDatasource.cursor(); ProjParameters projParameters = ProjParameters::find(); //purchTable.reread(); formDatasource.object(fieldNum(ProjProposalJour, ReasonCode)).mandatory(projParameters.DTOriginalInvoiceMandatoryReasonCode); formDatasource.object(fieldNum(ProjProposalJour, PaymMode)).mandatory(projParameters.DTOriginalInvoiceMandatory); if(projParameters.DTOriginalInvoiceMandatory && projProposalJourds.PaymentMethod == '') { throw error("The method of payment field is mandatory. Cannot proceed further."); } if(projParameters.DTOriginalInvoiceMandatoryReasonCode && projProposalJourds.ReasonCode == '') { throw error("The Reason Code field is mandatory. Cannot proceed further."); } next clicked(); } }

Thanks,

From your code,

1) You have defined the parameter buffer but not yet initialised a value for the buffer. So you need to call find method or write a select statement for the parameter table.

2) In the if condition where you are checking, it is not required to make those particular fields as mandatory when clicking post. Your code should be in such a way that on clicked of the post button, check the fields and if empty, and parameter is yes then throw error which will stop further execution.

So add a find for the parameter table and remove the mandatory related code and only check if value is empty if parameter is enabled and throw error if empty.

Cannot proceed further."); } if(projParameters.DTReasonCodeMandatory == NoYes::Yes && projProposalJourds.ReasonCode == '') { throw error("The Reason Code field is mandatory.

hi , everyone , i have made some changes in my code , plz suggest me if i need to make any changes ,

as i have added the condition that if
while select InvoicedNow from PSAProjProposalProj join projProposalJourds where PSAProjProposalProj.ProjProposalId ==projProposalJourds.ProposalId { if( PSAProjProposalProj.InvoicedNow <= 0) { } }

so if the reocrd in table is having the nagative value then only this condition works .

below is my code .

[ExtensionOf(formControlstr(ProjInvoiceProposalDetail,ProjFormLetter_Invoice))] final class DTInvoicepropCreditnt_Extension { public void clicked() { FormButtonControl formButtonControl = any2Object(this) as FormButtonControl; FormDataSource formDatasource = formButtonControl.formRun().dataSource(tableStr(ProjProposalJour)); ProjProposalJour projProposalJourds = formDatasource.cursor(); FormControl formControl = formButtonControl; FormRun formRun = formControl.formRun(); FormStringControl ReasonCode = formRun.design().controlName(formControlStr(ProjInvoiceProposalDetail, Reason_M_editReasonCode )) as FormStringControl ; PSAProjProposalProj pSAProjProposalProj; ProjParameters projParameters; select firstonly projParameters; while select InvoicedNow from PSAProjProposalProj join projProposalJourds where PSAProjProposalProj.ProjProposalId ==projProposalJourds.ProposalId { if( PSAProjProposalProj.InvoicedNow <= 0) { //formDatasource.object(methodStr(ProjProposalJour,editReasonCode)).mandatory(projParameters.DTReasonCodeMandatory); //formDatasource.object(fieldNum(ProjProposalJour, PaymMode)).mandatory(projParameters.DTOriginalInvoiceMandatory); if(projParameters.DTOriginalInvoiceMandatory == NoYes::Yes && projProposalJourds.PaymMode == '') { throw error("The method of payment field is mandatory. Cannot proceed further."); } if(projParameters.DTReasonCodeMandatory == NoYes::Yes && ReasonCode == null) { throw error("The Reason Code field is mandatory. Cannot proceed further."); } } } next clicked(); } }

thanks

Hi @Dineshkarlekar,

I see my first reply helped you, can you verify it, in order to help other who will face the same issue in the future.

I have a question for you why you use While select? You want to check all records?

I did some changes on your code, check it please:

[ExtensionOf(formControlstr(ProjInvoiceProposalDetail,ProjFormLetter_Invoice))]
final class DTInvoicepropCreditnt_Extension
{
public void clicked()
{
FormButtonControl formButtonControl = any2Object(this) as FormButtonControl;
FormDataSource formDatasource = formButtonControl.formRun().dataSource(tableStr(ProjProposalJour));
ProjProposalJour projProposalJourds = formDatasource.cursor();
FormControl formControl = formButtonControl;
FormRun formRun = formControl.formRun();
FormStringControl ReasonCode = formRun.design().controlName(formControlStr(ProjInvoiceProposalDetail, Reason_M_editReasonCode )) as FormStringControl ;
PSAProjProposalProj pSAProjProposalProj;
ProjParameters projParameters = ProjParameters::find();

while select InvoicedNow from PSAProjProposalProj
join projProposalJourds
where PSAProjProposalProj.ProjProposalId ==projProposalJourds.ProposalId
&& PSAProjProposalProj.InvoicedNow <= 0
{
//formDatasource.object(methodStr(ProjProposalJour,editReasonCode)).mandatory(projParameters.DTReasonCodeMandatory);
//formDatasource.object(fieldNum(ProjProposalJour, PaymMode)).mandatory(projParameters.DTOriginalInvoiceMandatory);
if(projParameters.DTOriginalInvoiceMandatory == NoYes::Yes && projProposalJourds.PaymMode == '')
{
throw error("The method of payment field is mandatory. Cannot proceed further.");
}
if(projParameters.DTReasonCodeMandatory == NoYes::Yes && ReasonCode == null)
{
throw error("The Reason Code field is mandatory. Cannot proceed further.");
}
}
next clicked();
}
}

Thanks,
Waed Ayyad

Hi Dinesh,

I can see that you started selecting projParameters as i first advised and that you stopped marking the fields as mandatory but rather checking the parameter value and if the field is empty.

So i'm glad it works now for you -- please don't forget to verify the answer

Now for your new condition, it seems you want to apply this condition based on each line that has the amount <0..if that's your intention then you can do that.. it depends on your business need ( i can't tell which tables or conditions you should use)

My comment is why do you join to projProposdlJourds again in while select if you already have it defined when you used formDataSource.cursor()

Wouldn't the following work?

while select InvoicedNow from psaProjProposalProj

where psaProjProposalProj.ProjProposalId = projProposalJourds.ProposalId && psaProjProposalProj.InvoicedAmount <0

Thanks,

Layan Jweihan
