Hi, as I understand, when we create ind req, we need to create in inactive versions in mc87 or in md61 and when we transfer we need to transfer in mc74 in active version. please explain why we need different versions in mc87 or in md61. what is the practical use of these versions while creating. does it mean, the requirements (example) from 01.10.2013 to 30.10.2013, should be one version and next month should be another version, is it like that. do we need to combine expected requirements from different customers for one period and put it as one version or is there any use?. can we use same functionality for long tern planning too also? if so how to use the same. please advise.
