Malaysian GST audit file (GAF)

Hello.

Our colleague in Malaysia requests to include Custom Fee (Called K1 and K2 value) in Malaysian GST audit files.

Sub system has these information so we're trying to send these K1 and K2 amounts to F0411  via F0411Z1.

We're looking for the following fields in F0411:

1. Where we can put amounts (numeric)

2. Fields need to be included in F0411Z1 because we need to import them

3. Users sometimes need to modify imported amounts so they need to be shown on JDE screen.

Is there any good field you can recommend?

Thanks,
