Dump CALL_TRANSACTION_NOT_FOUND

Hi All,

I have a dump while excuting program ZSMMENU.

Dump Analysis -

The current ABAP/4 program uses CALL TRANSACTION to call the Transaction

" ".

Table TSTC (Transactions) contains no entry for the

Transaction " ". This could be due to a program error

(incorrect transaction code specified).

Ensure that upper/lower case is correct.

Can anybody please give mevaluable inputs on this?

Thanks & Regards
