Error on Screen Exit

[Former Member]

Good day experts,

I would like to seek your help after I exhausted all possible solutions I knew in my mind and some research I did on net.

I am working right now in tcode, WB21, WB22, WB23 --Trading Contract...

My requirement is.

a. Add 5 additional fields/columns in tables WBGT/ WBHK/ WBHI (SAP standard trans table) and;

b. Add subscreens on the header and on the items. On the header screen, add 5 input fields. While on the item screen, add 20 input fields.

c. In this input fields, once the user saves it, it will be saved on the fields/columns added on the table, WBGT/ WBHK/ WBHI.

With this, I have found an enhancement which corresponds to my requirement. The enhancement is LWB2B001. This has three (3) FM exits and two (2) Screen Exits. I have successfully added the screens for the header and for the item. Now, I successfully added also the input fields in each subscreen, on the header and on the items. On the header, I can navigate from one tab to another.

My problem is on the item screen. Once I click it for the first time, it is ok. But when I click the other tab, an error now occurs.

The error message differs when I used different data samples. Here are the error messages

1. Entry 002 does not exist in TB2BK (check entry).

2. Item type for item 00001/material 8347841 could not be determined.

I hope I will hear some advises/solution to solve my problem. Thank you very much in advace.

Hi ,

Please check if you might have used some Standard fields on the item screen where those fields have the Check table .

thank you pal for your comment.

Eventually I solve it now. There was a problem in the data since the MATNR field is connected with trading contract. So the solution is, the functional consultant must do some configurations first. As an abaper, I dont know what is the specific config of it but what I am sure is, once you remove the material in the item, the subscreen works fine. You can click other tabs on the items subscreen. But if you include a material on the item list, then the new subscreen doesnt work anymore.

I hope it will give some points to everyone who works on screen-exits on tcode WB21, WB22 and WB23.

Hi Levi,

could you please tell me how you move the fields from screen exit into sap standard tables ?

Hi Toni,

First, append structures to this standard tables WBGT/ WBHK/ WBHI. The structures must corresponds to your screenfields. Use SE11 to append structures to this standard tables.

Second, after appending the structures, use the necessary exits. As far as I recall, we used a userexit I mentioned above. Also I implemented BADI WB2_ADDITIONAL_DATA to pass values from standard transactions like WB22.

I think these are the only thing that we did to implement such. Sorry but I can't give you the full detail now as I did this project almost three years now.

Levi
