You do rollover when the term of deposit is coming to an end and you want to extend the term of deposit to a few days, weeks, month etc.
At the time of rollover you can extend the terms of deposit, but also you can invest additional sum of money to your deposit.
When you don't invest - there won't be any postings.
But if you do - you have to show your investments with postings, also with postings deposit balance component in TRM is updated.
If you don't want the postings a) you have to create another invesment flow:
1. SM30 -> V_BWGART5: copy 1100 flow and rename it to RollOver flow.
2. SM30 -> V_ZBEWGRT5: assign new flow to product and transaction types.
3. SM34 -> TRDCV_DFLOWTYPE2: copy MM1100- update type and assign to "1. Transaction management" usage.
4. SM30 -> V_ATFTA: use contract type "5.Money market", Flow type from 1), Direction "Outflow", Update type from 3).
5. SM30 -> TRACV_DFT_REL: for update type from 3) uncheck checkmark "Relevant for postings"
Next time you do rollover, you have to enter your new flow for rollover and it won't be relevant to postings.
