Error ABAP_PROGRAM_DOES_NOT_EXIST

Hi,

I'm customizing a RapidMart (under DS 4.1) and hence developped 2 new ABAP programs. But at runtime at I got an error :

RFC_ABAP_EXCEPTION-(Exception_

Key: ABAP_PROGRAM_DOES_NOT_EXIST, No pager numbers are maintained for this address)[SAP NWRFC 720][SAP Partner 702 ][TST][saptst][DS_USER][1100]>.

I'm not familiar with SAP so my guess is that I gave a wrong name. Or the name should be declared first somewhere ?

Thanks for your input !
