Dynamic selection screen parameter

[Former Member]

Hello All,

I am facing problem in dynamic parameter declaration in selection screen. My requirement is as below,

Want to have 2 parameters in selection screen and based on first parameter (table fields) selected value, the second parameter (display the value of the selected table field) should display value of the selected field.

The problem is the second paramter type should be of first parameter selected field.

How to declare parameter dynamically after getting the first parameter selected field.

Thanks in Advance.

Regards,

Suganya.

hi

You may use the Runtime Type Information(RTTI)/ RTTS to get the parameter type at runtime

Process would be :

> create a variable: l_var type ref to CL_ABAP_ELEMDESCR.

> l_var ?= cl_abap_typedescr=>describe_by_data(parameter).

> loop at l_var->components into wa

> process.

> endloop

Hi,

As per my understanding you should try search helps.

Create elemantery search help if the fields are from single table else create collective search help.
