How to call this typical method

[Former Member]

Hi friends,

How are you all doing...

Can any one say how to call method 'on_costing_component_to_outtab' which belongs to the class 'cl_im__gui_itemization_ck'. Here the problem is two of this method parameters l_cl_cost_estimate & l_cl_costing_component are referred to further classes.

I declared in below faction and it is working fine when this method has normal code. Inside this method if some other class method is call then it is giving dump saying that paramether l_cl_cost_estimate & l_cl_costing_component are passed null and could not recognious until runtime. So how to make this method to work, there is one more class method called inside of this method. If i am creating objects for l_cl_cost_estimate & l_cl_costing_component then it is saying sub classes cannot be created.

Please give guidance for this so that i proceed further. Its very urgent friends.

Data: l_cl_exm_im_gui_itemization_ck TYPE REF TO cl_im__gui_itemization_ck,

l_cl_cost_estimate TYPE REF TO cl_cost_estimate,

l_cl_costing_component TYPE REF TO cl_costing_component.

create object: l_cl_exm_im_gui_itemization_ck.

CALL METHOD l_cl_exm_im_gui_itemization_ck->if_ex_gui_itemization_ck~on_costing_component_to_outtab

EXPORTING

im_execution_service = l_ck_execution_service

im_cost_estimate = l_cl_cost_estimate "class

im_costing_component = l_cl_costing_component "class

im_gui_currency = l_ck_ewknz

CHANGING

help full answers will be rewarded friends

Hello Srikanth

You cannot provide empty reference variables to the method but you need to have <b>instances </b>of CL_COST_ESTIMATE and/or CL_COSTING_COMPONENT.

The CONSTRUCTOR method of CL_COST_ESTIMATE has an optinal parameter IM_QUANTITY (of type CKBK_QUANTITY) and

CL_COSTING_COMPONENT has an optional parameter IM_QUANTITY (of type CKF_QUANTITY).

Based on your business scenario you have to provide reasonable values for these importing parameters and create instances of both classes. These instances are then "fed" to method ON_COSTING_COMPONENT_TO_OUTTAB.

Hello Uwe Schieferstein,

When i am creating objects for this class cl_cost_estimate & cl_costing_component then it is giving error message sub classes are not allowed to create instances. Yet I am unable to solve this problem. If possible try to test in zprogram by call in this method.

Its not allowing me to create object in this faction.

l_cl_cost_estimate type ref to cl_cost_estimate

l_cl_costing_component type ref to cl_costing_component

then it is saying sub classes cannot be created.

Pls try this friends..

Thanks & Regards,

Chitupolu Srikanth..

You can create instances of Class <b>cl_cost_estimate</b> using method <b>create_simple</b> or <b>create_from_db_table</b>.

This class in declared with the attribute "Creation of Instances" as Protected, so the only ways to create an Instace are declaring an Inheriting class and then use the Instance method "Constructor" or create a new class, setting <b>cl_cost_estimate</b> as a friend, and then again call the method Constructor. Otherwise, you can use static methods to get an Instance of the class, and the correct methods are those mentioned above (they return an instance of the object itself).

As Static Methods (with ret parameter), you can call these like

lr_cost_estimate = cl_cost_estimate=>create_simple( EXPORTING .... )

.

For class cl_costing_component, you can simply create an instance directly using Constructor (CREATE OBJECT <ref_obj>).

Hope this helps,

Roby.
