ABAP Object

hi there,

I'm so new to SAP and ABAP and i want so bad to learn it

so i went and i got ABAP Objects: An introduction to Programming SAP Applications.

I did install the CD 1, and 2. everything was great.

I log in to the system and i went to the snd chapter of the book. the tutorial was really good, but i found a problem witting the first program.

when ever i put the name S_first_program as an object i get an error box saying "user ddic can't change the customer information" so i thought about changing the name like Z_first_program. And Again I get the same ERROR

I log off and i change the user to bcuser i think

I got the same problem.....

I hope that i hear from you all.

thank so much

ahmed
