We would like to add an IT0057 (Membership fees) to PA70. We are trying to add IT0057 in table T588Q, the message appear "screen
4000 does not exist. Same goes if we change to screen 5000, 4100 or 5100. Currently, for IT0057 in PA30 we use screen 2000. When we add IT0057 with
screen 2000 in PA70 menu and try to execute the infotype in PA70 the message 'status FINS of the use interface MP005700 missing'. As we know,
PA70 use screen 4000 and 5000. but when we try to add in PA70 menu, the message is as mentioned above (screen 4000/5000 does not exist).
1) Does it mean we have to use SE51 to copy from module pool MPMMMM00 screen 4000 and 5000 to module pool MP005700 and then config for IT0057 in table T588Q ?
2) Does SAP permit our ABAPer/Functional to do such modifications ? Is it define as customizing or customization ?
