Equipment Additional Subscreen - Requested function is not available here

Hi Experts,

I need to add a Waranty subscreen in Equipment master data.

To achieve that requirement, I've done the following tutorial:

http://scn.sap.com/people/antony.thomas/blog/2010/08/12/enhancement-to-support-multiple-warranties-per-equipmentadditional-data-tab-in-ie010203

The outline of the tutorial is as follow:

• Register profile for Warranty in SPRO
• Create the subscreen
• Call the Subscreen using function module EXIT_SAPLITO0_001 in exit ITOB0001
• Implement BAdI EQUI_UPDATE to insert the Warranty data.

Everything goes fine, the subscreen and its the warranty table appear.

However when I tried to input the data into the ALV table, an error message appear.
It told me "Requested function 19 is not available here"

I tried to search related error in the SCN and stumbled into this forum thread

Screen Enhancement for Equipment Creation IE01 | SCN

However, the information in the thread is not yet answered.

Regards,

Suwandi
