Using Custom Controllers

Hi,

I have a requirement wherein Iu2019ve to make certain fields (Project Start Date, Project End Date, Currency, Revenue Projections, Primary Unit Involved, Other Units involved) non-editable when PROPOSAL exists.

Iu2019m following the below mentioned approach :

u2022 Calling function u2018CRM_DOC_FLOW_READ_DBu2019 in DO_PREPARE_OUTPUT ( in IMPL class) to return the follow-up transactions of current Opportunity transaction.

u2022 Setting the value of a flag variable accordingly.

u2022 Using a custom controller to retrieve the value of the same flag variable in GET_I_XXX ( in CN class) method.

Iu2019ve written the code at both the places, but in the GET_I_XXX method, it gives me the following error when I try to invoke the get_cutom_controller method : u201CMethod GET_CUSTOM_CONTROLLER is unknown or PROTECTED or PRIVATEu201D.

Can someone enlighten me on this?

Any pointers would be of great help.

TIA.

Regards,

Richa.
