CL_RSPLS_CR_EXIT_BASE how to use the create method
I am using a copy of CL_RSPLS_CR_EXIT_BASE in the relationships derivation of our planning project. I do not understand how CL_RSPLS_CR_EXIT_BASE works.
Here is the problem:
I use the class to derivate 0COSTCENTER from 0CO_AREA and 0COORDER. In one planning function everything works fine. With the use of the relationships the class is called and in the DERIVATE Method I can select the responsible costcenter from the 0COORDER data with 0COORDER and 0CO_AREA.
But I also have a planning sequence which is also using the relationships but on step 7 (costcenter from co_area and coorder) it directely calls the DERIVATE method. But in the DERIVATE Method I do not have the source fields COORDER and CO_AREA as source data available....
How does this work? Where do I get the source data from? In the first case I have it all in the parameter c_s_chas.... but in the CREATE method I can't find the source data.
Thanks for any input.
Have a nice day
