message id is used to tell the program which message class is being used in this program.

If in the program there is a statement like this.

message E000.

The program will issue the error message 000 of message class CO.

The message class can be omitted. Triggering a message would then look like this.

Message E000(CO).

Type-pools are kind of like include programs, they hold TYPES statements which can be referenced in your program. So instead of you having to code your own types, say for instance a field catalog for ALV, you can just reference the type from the type-pool SLIS.

If this post has been helpful, pleae award points accordingly. Thanks.

message id => when you want to issue messages from your program to the users , you can use the message defined under this message id.

type-pools => a collection of predefined variables. instead of defining variables in each and every program, just define it once in a type pool. this addition type-pools:co will allow you to use all the types declared within the typ-pool in your program.
