Is it possible to change the name from the field settings after adding?
No, name is set when the field is created and must be unique for the field within a single table.
To change the name, there is a special tool that can be called from the context menu in the field header.
If the codes in the other fields access the field whose name is changed, will they work after the change?
No, the codes will not work because the name (address) of the field has changed.
Will the name of the field in the codes of the other fields be changed automatically or it must be changed manually?
Nothing will change automatically. Therefore, if you change the name, you must also change all related codes.
The Change name tool shows the tables and fields where the current name is used, with the ability to navigate to these codes and change them manually.
Only codes where the use of name can be unambiguously determined are shown — it is specified through #, @, or in single quotes in a function parameter with a clear table indication.
Will the values in the field be preserved when its name is changed?
Only for simple tables and cycle tables. If you change the name in the calculation table inside the cycle or in the tree, the data will be lost when recalculating this table!
Is it possible to change the placements without losing values?
If you move a field between the header and footer. If from inline part to block part or vice versa — it will not be saved.
What prefixes are fields created with in this or that placement?
For the lowercase part, the field is created without a prefix.
h_ — for the header.
fl_ — for the prefilter.
f_ — for the footer.
