Calling custom Infotype method from ABAP report

Hi Experts,

I am working on an application where i need to call a method of a custom defined infotype.

I have done this -->

1. Create a custom infotype 9111

2. SAP creates a class of that infotype ZCL_HRPA_INFOTYPE_9111

3. Inside this method there are few inherited method which provide me functionality of insert , update , delete

i want to call methods IF_HRPA_INFTY_BL~MODIFY,

IF_HRPA_INFTY_BL~INSERT

However when i call these method from abap report this method does not work.

where as when i try to insert an entry using PA30 transaction it works.

Does anyone know why does this happen and what is the solution?

Regards,
