Hi,

Make the field type as listbox with key in the screen layout editor and assign function codes. Then you can use the function module VRM_SET_VALUES for populating the search help.

like in the pbo you will populate the list for first field.

on selecting a value the control goes to PAI with the function key for field1. There do the validation and select for the second field. Like the same for the other field also.

Use the type pool VRM in top include for using the function module.

Renjith Michael.

Hi,

First use VRM_SET_VALUES to get popup from first table. Now use FM DYNP_VALUES_READ to read the value that has been provided in the first screen field. Now based on that read the values through DYNP_VALUES_READ and for the third one get the values based on the second selection screen value.

Thanks and regards,

Atanu

Hi,

If you feel 'VRM_SET_VALUES' to be difficult to use, then you can use the function module F4IF_INT_TABLE_VALUE_REQUEST also.

Just refer to the standard program demo_dropdown_list_box.
