Validating Screen Fields in FD32 - BTE 1520

costas_lampropoulos — Tue, 15 Jul 2014 11:32:37 GMT

Hello everyone,

I have a requirement to make various checks before saving in FD32. For example I want to make sure that KNKK-DBEKR will be less than or equal to KNKK-KLIMK.

I have searched SCN and I have implemented BTE 1520 (you can see an example thread here).

My problem is that while in BTE 1520 I don't have the screen fields available (or at least I don't know how to make them available to my function module).

Has anyone done something similar?

Thank you in advance.

Typically you don't want to look at the screen fields. Instead you want to look at the X and Y variants of the DB structures.

Thanks Neal, but I already tried that. The function module (a copy of SAMPLE_INTERFACE_00001520) uses only two variables I_KUNNR and I_KKBER.

As you can see in the screenshot below (from the debugger), I have been trying to find whether I have anything else available at that point.

I had just finished checking. And agree, however:

but the rule applies. there will be variants on the DB structure that you want to read.

If I get time later today, I'll dig around further.
