We can help. Together we learn....

 

Sometime the requirement is such that search help is required from the values obtained in run time or from constant values. In this you can use the FM: F4IF_INT_TABLE_VALUE_REQUEST to meet your purpose. The basic logic is that it uses data from the internal table to show in the F4 search help.

 

Example: Here an internal table is populated with some constants. This program is just for guideline.

 

* Type for internal table for populating the file-type

 Types: BEGIN OF x_filtyp,

              filetype TYPE char3,          " File type

              description TYPE char50,      " description

             END OF x_filtyp.

You can add your code in AT SELECTION-SCREEN for establishing dependency on two or more selection screen parameters.

 

Example:

 

PARAMETERS: p_matnr TYPE matnr,
p_check TYPE char1.

AT SELECTION-SCREEN.
IF p_matnr = '000000000000000023' .
p_check = '1'.
ELSEIF p_matnr = '1697'.
p_check = 2.
ENDIF.

  

 

Output

For P_matnr = 23 (selected by user), p_check will be automatically populated 1 and 2 for p_matnr = 1697.
