?To use parameter IDs, you need to ?set? (store) values in the global memory area and then ?get? (retrieve) values from this parameter ID memory area.

?In the case of an online program, you will ?set? values from screen fields and you will ?get? these values for screen fields.

?You can perform this ?set/get? function two ways:

? Use the ABAP statements ?SET PARAMETER ID? and ?GET PARAMETER ID?.

? Use the field attributes ?SPA? and ?GPA?.

?Remember that parameter IDs can only be used with ABAP Dictionary fields because parameter IDs are linked to data elements.  The appropriate data elements must have a parameter IDs for this ?set/get? function to work.
