Control visibility of standard fields

→ For this purpose so called expressions are used.

Click in mask editor into a field.
In local menu use the item Edit visible expression.
A new window opens.
Here you can define a term.

Example: if (fk_ort_mc_vers = 'DEBRE' OR fk_hafen_mc_vers =[DEHAM], 1, 0)
Explanation: IF (Place of receipt = DEBRE OR Port of loading = DEHAM THEN visible, otherwise invisible.)

Construction:
If (Condition, True, False)
True stands for visible, false for invisible.

The simplest expression is the following:
If (1=1, 1, 0)
If 1=1 then visible, otherwise not visible.

Note: Operators like >= (greater or equal), = (equal), <= (less than or equal), =! (not equal) are possible.

Then, use in local menu the item Finish mask editing. Click in the saving dialog in Yes.

Do not use in environment menu the function File → Save. The expression is not saved then!

Global placeholders

Global placeholders can also be used.
→ For a list, see entry insert placeholder in the local menu of the additional mask fields.

Example: if (MANDANT = '001', 1, 0)
Explanation: The field is only displayed if the current client is 001.

Hint: Unlike the mask additional fields the global placeholders are not enclosed in square brackets.

Edit visibility

Here the field is switched visible or invisible.

You can also refer to another field and make the field editable depending on it: Only the entry in another field makes the field editable.

Example: CC_eawb=Y causes the field to be disabled until the checkbox of the field CC_eawb = Y, i.e. active is set.
