ABAP HIDE Statement syntax and functionality in SAP

HIDE

Short Reference

ABAP Syntax HIDE dobj.

What does it do? This statement stores the content of a variable dobj
together with the current list line whose line number is contained in sy-linno in the hide area of the current list level. The data type of the variable dobj must be flat and no field symbols or components of Boxed Component s can be specified that point to rows of internal tables, and no class attributes can be specified. The saved values can be read as followed:
Any user action on a displayed screen list that causes a list event assigns all values saved using HIDE to the relevant variables.

If a list row of a list level is read or modified using the statements
READ LINE or
MODIFY LINE , all the values of this row saved using HIDE are assigned to the relevant variables.

Latest notes:
The HIDE statement works independently of whether the list cursor was set. In particular, variables for empty list rows can be stored (that is, rows in which the list cursor was positioned using statements like SKIP
).

The HIDE statement should be executed directly in the statement that has set the list cursor in the row.

Using the HIDE statement on a field symbol can cause runtime errors. The syntax check displays a warning.

Example ABAP Coding Saving square numbers and cubic numbers for a list of numbers. The example shows that any variable can be stored independently of the row content. In the real world, one would more likely save only the number and execute the calculation, when required, in the the event block for AT LINE-SELECTION .
