F4 Help with Custom FM works on GUI and fails on WEBUI

[Former Member]

Hi,

We're on SAP ERP 6.0 EHP7. I have implemented similar solution, that is, to use check fm instead of check table.

My *_F4 fm for the characteristic works on GUI side:

However, it errors on WebUI side for the same characteristic:

Have you encountered or are you aware of this issue? Any help on how to resolve this?

Thanks in advance.

Hi,

I am posting the solution I followed so it could help somebody with similar requirement.

I did some research online and found that following document.

https://help.sap.com/saphelp_globext607_10/helpdata/en/c5/463da114bc4689bbbdd98721c28a8c/frameset.ht...

According to this doc, Function modules used by the back-end transactions are not supported on PLM WebUI. So, Instead of calling the FM F4IF_INT_TABLE_VALUE_REQUEST or similar FM to show the pop up screen for F4 help, the values are just exported from the value help FM attached to the characteristic so that the standard WebUI logic handles the popup for F4 help. And I have implemented the BADI BADI_EHSS_SPEC_VAL_CHECK to add validations on the field on WebUI.
