Module-pool: List-Box

Former Member — Sun, 17 Apr 2011 09:39:26 GMT

Hi,

I am customizing a Z- module pool transaction.

Below is my requirement.

I am displaying shipment numbet in I/O field.

If LoadID exists for more than one shipment, display other shipments as drop-down.

When the transaction is executed for the first time, I should be able to enter the shipment no., then based on LOAD ID, I should display multiple shipments in the same I/O field.

I am using the FM : vrm_set_values.

But, m not able to achieve this.

Hi,

The function module VRM_SET_VALUES is used to fill the value list associated with a List Box .This FM uses types which are declared in type group VRM. So

we should declare TYPE-POOLS VRM before using this FM.

Some important types declared in the VRM type group are

VRM_ID

It refers to the name of the input/output field associated with list box

VRM_VALUES

It refers to the internal table consisting of two fields TEXT(80C) and KEY(40)C

that will be used to create the list values.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

ID = name of screen element ,it is of TYPE VRM_ID

VALUES = internal table containing values,of TYPE VRM_VALUES
