You can create custom specific PA infotypes by using t-code PM01. Custom specific infotypes are numbered between 9000-9999. Following are the main steps to follow:
1. Goto transaction PM01 – Create Infotype 2. Enter the Infotype no., select PS Struture radio button under Subobjects and click on Create All tab. This will create the Module Pool, interface screen, customising table entries and data dictionary objects for your infotype. 3. You will be directed to the Data Dictionary screen where you will define the PS structure components and types. Save and activate the PS Structure (PSnnnn). 4. Next you customise your Infotype attributes like Time contraints etc in view table V_T582A and mention technical data details like Screen number (2000 for single screen and 3000 for list screen), dialog module – RP_nnnn and database table PAnnnn etc. 5. Finally you go to Screen Painter and edit your interface screen 2000. Save and activate the screen.
You do not need to create/change the module pool program MPnnnn00 as it it automatically generated by PM01 using the Pnnnn structure.
