Hi Enrique,
1. To find out which fields are hidden in your Equipment Master run Transaction OIAD or OIAF as the case may be. OIAD id for Equipment specific fields and OIAF is for fields which appear in both Equip and FLocn. These are customising Tcodes. Now let's suppose you want to enquire about hidden fields in a particular Equipment Category (in your picture it is L), then:
Run OIAD / OIAF --> Click on Influencing as shown in the picture --> Double click on Equipment Category --> Put L in the field and press Enter. Now you will be presented the Equipment category specific settings. Scroll down the fields to find out which are selected Hide Radio Button.
2. To have Additional fields in Equipment Master, go through this document User-Fields in Equipment, Functional Location, Fleet Masters To have the visibility of these custom fields as per Country, you can have your code in the PBO module of the sub-screen, like:
IF ....... = 'X'. "country condition
LOOP AT SCREEN.
IF SCREEN-GROUP1 = '001'.
SCREEN-INVISIBLE = '1'.
MODIFY SCREEN.
ENDLOOP.ENDIF.
The code suggested above might not be that simple for your requirement. It is just a sample. You need to develop the same. Hope this post helps you.
