Can anyone give me a clear picture regarding standard document types?

Hi DMS Experts,

What are the main use of the std doc types - EBR,D01,Q01 and Q02 . I know that EBR is for batch input , D01 for print list , Q01 for Quality Agreement and Q02 for Technical Delivery Team . They are non editable and can be created after deleting only . For D01, I have found that Alternative screen is 902 and Alt screen exit is 'OADVS902'.

and for EBR , it is '903' and 'PPPIF903' respectively.

Are these values mandatory for the doc types EBR and D01. Also I have seen that for the above doc types,Kpro content server is not checked.

Can we store them in Kpro content server also..?

Thanks and Regards
