shrgrl,

In short,

Delivery Class A means the data of the table will be updated by the application programs.

Delivery Class C refers the table as a customer table where in the data will be entered only by the customer.

You can refer the LINK1 and LINK2 for more details.

Regards!

Thanks for reply. I know this. I created two tables of type 'A' and 'C'. I add data with Abap code. I thought I couldn't add data to the table I created with C, but they both work the same. Is there a live demo where I can see the working logic of C? Sorry, I am new to Abap and have difficulty understanding.

In simple terms

If your refer the customer specific configuration entries in spro tcode . Those Related tables are type ‘C’.
eg: T000, T001, T005 etc

the changes it will ask for customising transport.

But in A type table we could directly maintain eg: vendor master: LFA1 , Customer master KNA1 Etc

If you need direct maintaining in production select type A .

If transport path is mandatory go for type C.

Data will be getting saved in both type of tables with direct ABAP code in same way. But the basic purpose of Delivery class C, tables is to make some customizing change in customizing server and transport it to production system. No direct edit in Production Live system. I will ask customizing transport request when directly edited from SM30 or related Tcode.

Type C table are not usually updated with ABAP code.

We enable maintenance allowed and create Table Maintenance Generator(TMG) and maintain with SM30 tcode.
