Dear Expertise

I have created a ALV Webdynpro for EKPO.

I have taken 5 fields.

There's problem in Coding.

Output is as -

Actually when first screen opens , we should be able to select the PO no from the list . But second screen opens and includes the options.

Can anyone help me in this scenario?

Hi Varun,

If you go to SE11 and look Purchasing Doc. field it will have search help assigned to it and that is what you are seeing here. There are two ways either create your own search help or do what Ram says.

Thanks

waiting for the answer.

I have already posted my code and waiting for your answer.

Hi Varun,

Sorry for my late reply.

Your code seems to be correct. See once you got the error information at the bottom section of your ECC, just click on that error. It will automatically take to the coding area, where you are facing the error.

Please post that also, so it will be further easy to track on that error cause.

BR,

RAM.

when i am trying to execute the program, then only this error arises

500 SAP Internal Server Error

ERROR: Could not find attribute LOW (termination: RABAX_STATE)

what is attribute Low?

Is there any problem with my data declaration.

Help.

Regards

varun

Hi Varun,

Run your applicatoin and check for ST22 analysis, it will help us.

BR,

RAM>

Error analysis I have seen

"Could not find Attribute LOW"

The exception 'CX_WD_CONTEXT' was raised, but it was not caught anywhere along

the call hierarchy.

Since exceptions represent error situations and this error was not

adequately responded to, the running ABAP program

'CL_WDR_CONTEXT_NODE_INFO======CP' has to be

terminated.

The exception, which is assigned to class 'CX_WD_CONTEXT', was not caught and

therefore caused a runtime error.

The reason for the exception is:

Could not find attribute LOW

Help.

Hello Varun,

Check for the below points.

1. I think you have an attribute 'LOW' in your WDC, which has been deleted in Component but still you have it in View level. If yes, go for Update Mapping in your view context.

2. If you are sure that you have deleted this attribute in both component and view level, then check in your coding. You should be have surely used the attribute 'LOW' in some part of coding.

Let me know further.

BR,

RAM.

I have check there is no field or any attribute as LOW in WDC .

confused .

help.

Regards

varun

I am getting now selection screen . But now when i try to display data according to date.

Its throwing dump as-

The current application program detected a situation which really

should not occur. Therefore, a termination with a short dump was

triggered on purpose by the key word MESSAGE (type X).

Help

varun

Hello Varun,

This is your standard F4 configuration. If you need a F4 where you should directly see the PO list from the table, then you can go for cutom F4 like OVS. Please follow the below link.

Varun,

Please check the SDN link that I have attached in my earlier reply. It will be a straight forward approach.

BR,

I have created the design as -

output is

and my code on SUBMIT is as-

so why selection option is not coming.

I wanted my select options to be like f4 help.

Regards

varun

Hello Vaun,

This code if for your output result based on the action of SUBMIT button.

F4 concept is different. You want to create a OVS Event handler Method for your select option field. See page# 10 in the given doc(Check for previous reply).

BR,

RAM.

I have done same

Now error is coming as-

ERROR: Could not find attribute LOW (termination: RABAX_STATE)
