Function calls for standard project structure copy in SAP Project System
Creating an operative project structure in SAP project system based on a standard project structure or on another operative structure using BAPIs might be a very difficult task. The reason for that is that before the relevant BAPI for saving the new operative project structure could be called it would be necessary to select from the template project structure every single possible project object and sometimes there might be many. Among possible project objects we could list project definitions, WBS elements, network headers, network activities, network activity elements, milestones, material components, PS texts, relationships, etc.
Luckily for us SAP comes with two function modules that when called in the correct order and together with some other function modules do the complex work with possibly much less lines of code. The functions are “CJWB_PROJECT_COPY” and “CJDT_CREATE_ACT_FOR_NEW_PRJ”.
The first of the function modules is in charge of creating project definitions, WBS elements and other objects related to WBS elements (e.g. PS texts and WBS element milestones). The second function module is in charge of attaching standard network headers and their dependents objects (e.g. network activities, network activity elements, milestones, material components, etc.) to the objects previously generated by function module “CJWB_PROJECT_COPY”.
Among the function modules other than the ones already mentioned that also have to be called in order to successfully accomplish the standard project copy the most important are “CJDW_GET_NEW_NUMBERS” and “CJDT_GET_NEW_NUMBERS”. These function modules are in charge of replacing temporary internal numbers by correct internal numbers that will be updated to the database (e.g. OBJNR numbers).
Below are two sample codes for copying standard project structure. The first is a simple code for cases in which network headers are not necessary while the latter is a slightly more complex code for cases in which network headers are necessary. The second code sample also contains some lines for manipulating WBS element data (project responsible and applicant number) for demonstration purposes.
The sample are based on the calls performed in standard transactions CJ20N and CJ2B (includes LCNPB_MF4T, LCNPB_MF55 and LCJTRF3B).
Sample 1: Simple project structure without network headers

CALL FUNCTION 'CJDW_GET_NEW_NUMBERS'. CALL FUNCTION 'CJDT_GET_NEW_NUMBERS'. SET SCREEN 0. COMMIT WORK.
