[Former Member]

Hello,

I´m trying this guide: "End-to-End How-to Guide: Building SAPUI5 Applications on SAP NetWeaver AS ABAP 7.31 Consuming Gatew...

On page 19 when typing the code. The line

FIELD-SYMBOLS <lf_entityset> TYPE zcl_epm_products_mpc_base=>ts_epmproduct.

produces the error message "TYPE ... is unknown".

Any suggestions? I´m a newbie.

Hi Kai,

Can you try to change the statement as

FIELD-SYMBOLS <lf_entityset> TYPE zcl_z_epm_products_mpc_base=>ts_epmproduct

Hi Kannan,

doesn´t work. Now The type "zcl_z_epm_products_mpc_base=>ts_epmproduct" is unknown...

If I´d know, what this type stands for or represents, then maybe i could find out what it´s meant to be called...

Hi Kai,

Do you implemented the method by using redfinition button rather than directly coding.

Hi Kai,

Can you check the status of the class in the SE24.and check for the attribute.

I load the classbuilder (SE24), Select the method EPMPRODUCT_GET_ENTITYSET, Then I see the same code as I just wrote (The code from the tutorial).

What do you mean by "Check the status of the class/attribute?"

Thx for your help so far!

Hi Kai,

In SE24  you put the class as zcl_epm_products_mpc_base and go to attributes and check whether class attribute ts_epmproduct exists.

Hi Kai,

Finally i found the solution.It will work for you.

use ZCL_Z_EPM_PRODUCTS_MPC instead of  zcl_epm_products_mpc_base class.

Hope it answers your query.

One that I'm working on didn't have the attribute, ts_epmproduct for class ZCL_Z_EPM_PRODUCTS_MPC.

So I'm using following what's recommended and it activates but doesn't return the result but error page.

<lf_entityset> type ZCL_Z_EPM_PRODUCTS_MPC=>ts_bapiepmproductheade

Any ideas?
